I'm trying to get data from an Excel file on a button click event. My connection string is:
string connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\source\\SiteCore65\\Individual-Data.xls;Extended Properties=Excel 8.0;";
When I click on the button, I got the following error:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
I have no clue how to fix this. My operating system is Windows 7.
Well, you need to install it. You're looking for:
The 2007 Office System Driver: Data Connectivity Components.
A 64-bit version of the 'Microsoft Access Database Engine 2010 Redistributable' that will allow you to use the 'Microsoft.ACE.OLEDB.12.0' provider is available here:
http://www.microsoft.com/en-us/download/details.aspx?id=13255
If you use the download from the accepted answer, you will need to build for x86, as pointed out by #backtestbroker.com.
depending on the app(32/64bit) using the connection you could just install
Access 2007 engines (only 32bit)
Access 2010 (32&64bit)
Access 2013 full runtime (32&64bit ! >200mb)
Access 2016 runtime
Access 2019 runtime
Summary:
all offices from 2007-2016 contain the provider "Microsoft.ACE.Oledb.12.0"
depending on your application architecture choose the appropriate runtime engine (32/64)6
check your providers with the powershell-command from both 32 and 64bit shell:
(New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
and you will see which provider your system can use
the long story:
the strings can be found with http://live.sysinternals.com/strings.exe
eg. on a 64bit System with 32bit drivers installed
strings.exe -u -n 10 "c:\Program Files (x86)\Common Files\microsoft shared\OFFICE12\MSO.DLL" | findstr "ACE.O"
strings.exe -u -n 10 "c:\Program Files (x86)\Common Files\microsoft shared\OFFICE14\MSO.DLL" | findstr "ACE.O"
strings.exe -u -n 10 "c:\Program Files (x86)\Common Files\microsoft shared\OFFICE15\MSO.DLL" | findstr "ACE.O"
even in the upcoming office 2016
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX64\Microsoft Shared\OFFICE16\MSO.DLL
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX86\Microsoft Shared\OFFICE16\MSO.DLL
you will find the strings
Microsoft.ACE.OLEDB
Microsoft.ACE.Oledb.12.0
the Office 2013 comes also with csi.dll
c:\Program Files (x86)\Common Files\microsoft shared\OFFICE15\Csi.dll
c:\Program Files\Common Files\Microsoft Shared\OFFICE15\Csi.dll
which contains the "Microsoft.ACE.OLEDB.15.0"
and Office 2016
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX64\Microsoft Shared\OFFICE16\Csi.dll
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX86\Microsoft Shared\OFFICE16\Csi.dll
which has the "Microsoft.ACE.OLEDB.16.0" version
The first thing you need to check is your build configuration of your application.
If you have built your project under x86 platform, then in order to
resolve you issue you should install the following packages on your
machine:
In order to use the 'Microsoft.ACE.OLEDB.12.0' provider you must
install the Microsoft Access Database Engine 2010 Redistributable
first, this installation is available at:
http://www.microsoft.com/download/en/details.aspx?id=13255 .
After the installation has complete, try running you application, if this
solves the issue great, if not, continue to step 2.
This next step is an unexplained workaround, which works for Office
2010, even though it is the Data Connectivity Components of Office 2007. I am not quite sure why this works, but it does and this has been proven to work in almost all cases. You need to install the 2007 Office System Driver: Data Connectivity Components, this installation is available at:
http://www.microsoft.com/download/en/confirmation.aspx?id=23734 .
After this installation is complete, try running your application, this should resolve the issue.
If you are trying to run an application built under x64 or AnyCPU
platform, I would recommend first validating that it runs as expected
under the x86 platform. In the event that it does not run under that
x86 platform, perform the steps in the first part and validate that
it runs as expected.
I did read that the MS Access drivers including the OLEDB Database
driver works only under the x86 platform and is incompatible under
the x64 or AnyCPU platform. But this appears to be untrue. I
validated my application was running when building x86, then I
installed the Access Database Engine using the passive flag.
First download the file locally You can download the installation
here: http://www.microsoft.com/en-us/download/details.aspx?id=13255
Installing using the command prompt with the '/passive' flag. In
the command prompt run the following command:
'AccessDatabaseEngine_x64.exe /passive'
After these 2 steps I managed to run my application after building in
x64 or AnyCPU build configuration. This appeared to solve my issue.
Note: The order of the steps seems to make a difference, so please follow accordingly.
I got this error/exception in Visual Studio 2010 when I changed my build in the Configuration Manager dialog box from "x86" to "Any CPU". This OLEDB database driver I understand only works in x86 and is not 64bit compatible. Changing the build configuration back to x86 solved the problem for me.
I installed the MS drivers and it still didn't work for me. Then I found this blog post that solved the issue. Read it there, else use these two images (linked from that post) as the TLDR sumamary:
Although many answers have been given, the problem I encountered was not yet mentioned.
My Scenario: 64-Bit Application, Win10-64, Office 2007 32-Bit installed.
Installation of the 32-Bit Installer AccessDatabaseEngine.exe as downloaded from MS
reports success, but is NOT installed, as verified with the Powershell
Script of one of the postings above here.
Installation of the 64-Bit installer AccessDatabaseEngine_X64.exe reported a shocking error message:
The very simple solution has been found here on an Autodesk site.
Just add the parameter /passive to the commandline string, like this:
AccessDatabaseEngine_X64.exe /passive
Installation successful, the OleDb driver worked.
The Excel files I am processing with OleDb are of xlsx type, produced with EPPlus 4.5 and modified with Excel 2007.
For all those still affected by this.
I've been getting the error...
OLEDB error "The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine."
...as described by the OP, Shailesh Sahu.
I have 64bit Windows 7.
My problem is within PowerShell scripts, but is using a connection string, similar to the OP's post, so hopefully my findings can be applied to C#, PowerShell and any other language relying on the "Microsoft.ACE.OLEDB" driver.
I followed instructions on this MS forum thread: http://goo.gl/h73RmI
I first tried installing the 64bit version, then installing the 32bit version of the AccessDatabaseEngine.exe from this page
http://www.microsoft.com/en-us/download/details.aspx?id=13255
But still no joy.
I then ran the code below in PowerShell (from SQL Panda's site http://goo.gl/A3Hu96)
(New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
...which gave me this result (I've removed other data sources for brevity)...
SOURCES_NAME SOURCES_DESCRIPTION
------------ -------------------
Microsoft.ACE.OLEDB.15.0 Microsoft Office 15.0 Access Database Engine OLE DB Provider
As you can see, I have Microsoft.ACE.OLEDB.15.0 (fifteen) not Microsoft.ACE.OLEDB.12.0 (twelve)
So, I amended my connection string to 15 and it worked.
So, a quick PowerShell snippet to demonstrate how to soft-code the version...
$AceVersion = ((New-Object System.Data.OleDb.OleDbEnumerator).GetElements() | Where-Object { $_.SOURCES_NAME -like "Microsoft.ACE.OLEDB*" } | Sort-Object SOURCES_NAME -Descending | Select-Object -First 1 SOURCES_NAME).SOURCES_NAME
$connString = "Provider=$AceVersion;Data Source=`"$filepath`";Extended Properties=`"Excel 12.0 Xml;HDR=NO`";"
amended to pick the latest ACE version, if more than one
Hopefully, anyone finding this can now check to see what OLEDB version is installed and use the appropriate version number.
If you're using 64-bit but still having problem even after installing AccessDatabaseEngine, see this post, it solved the problem for me.
i.e. You need to install this AccessDatabaseEngine
You need to change the Solution Platform from "Any CPU" to "x86" or "x64" based on the bitness of office installation.
The steps are given below:
Right click on the Solution File in Solution Explorer:
Click on the Configuration Manager.
Click on the Active Platform Drop down, if x86 is already there then select that, else click on New.
Select x86 or x64 from the new platform dropdown:
Compile and run your application.
do this 2 steps:
in this menu: project -> yourproject properties... -> Build : uncheck "prefer 32-Bit"
in connectionString : write cuotes before and after Extended properties, like this: Extended Properties='Excel 12.0 Xml;HDR=YES'
var fileName = string.Format("{0}", openFileDialog1.FileName);
var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0}; Extended Properties='Excel 12.0 Xml;HDR=YES'", fileName);
var adapter = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", connectionString);
var ds = new DataSet();
adapter.Fill(ds, TableNmae);
DataTable data = ds.Tables[TableNmae];
dg1.DataSource = data;
I was able to fix this by following the steps in this article: http://www.mikesdotnetting.com/article/280/solved-the-microsoft-ace-oledb-12-0-provider-is-not-registered-on-the-local-machine
The key point for me was this:
When debugging with IIS,
by default, Visual Studio uses the 32-bit version. You can change this
from within Visual Studio by going to Tools » Options » Projects And
Solutions » Web Projects » General, and choosing
"Use the 64 bit version of IIS Express for websites and projects"
After checking that option, then setting the platform target of my project back to "Any CPU" (i had set it to x86 somewhere in the troubleshooting process), i was able to overcome the error.
If you are debugging a web project, just make sure IIS Express is running either in 32 or 64 bits depending on your project settings.
Goto
Tools > Options > Projects and Solutions > Web Projects
and from there check (or uncheck) the 'Use 64 bit version of IIS Express...'
If the installed "AccessDatabaseEngine" still does not help, below is solution:
You need to change the Active Solution Platform from "Any CPU" to "x86".
OLEDB Provider is Not Registered on the Local Machine
From CodeProject.com
First verify which version of microsoft.ace.oledb.12.0 is installed in your system.
Check in below path C:\Program Files\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL --64 bit is installed
Check in below path C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL --x86 bit is installed
If (x86) is installed then using configuration manager change solution platform to x86, for x64 change to x64.
If not available then install using below link
https://www.microsoft.com/en-us/download/details.aspx?id=23734
A 64-bit version of the 'Microsoft Access Database Engine 2010 Redistributable' that will allow you to use the 'Microsoft.ACE.OLEDB.12.0' provider is available here:
http://www.microsoft.com/en-us/download/details.aspx?id=13255
If using VS 2012 or later, make sure that "Prefer 32-bit" checkbox is unchecked in the project's Properties => Build => General configuration
syp_dino,
The solution for me as you suggested for the "Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine" error is to change the Active Solution Platform from "Any CPU" to "x86".
When I performed those steps, rebuilt the solution, grabbed the EXE and placed in on the network, everything worked smoothly on the Windows 7 64 bit machine.
I faced this same problem. Go to the Solution Properties and change Any CPU to x86, I think it will do the job.
These configurations worked in January of 2020 on my new machine build:
(1 - x64 only) Windows 10 x64, Office 365 x64, AccessDatabaseEngine_x64 2016 installed with /passive argument, VStudio build settings set to x64 explicitly, with the following connection string: Provider= Microsoft.ACE.OLEDB.16.0; Data Source=D:...\MyDatabase.accdb
(2 - x64 or x32) Windows 10 x64, Office 365 x64, AccessDatabaseEngine_x64 2016 installed with /passive argument, PLUS AccessDatabaseEngine 2010 (32bit) installed with /passive argument, VStudio build settings set to AnyCPU, with the following connection string: Provider= Microsoft.ACE.OLEDB.16.0; Data Source=D:...\MyDatabase.accdb
(3 - x32 only) Windows 10 x64, Office 365 x32, AccessDatabaseEngine 2010 (32bit) installed with /passive argument, VStudio build settings set to x86, with the following connection string: Provider= Microsoft.ACE.OLEDB.12.0; Data Source=D:...\MyDatabase.accdb
FAILURE NOTES
Using the ACE.OLEDB.12.0 x64 provider in the connection string failed with only the AccessDatabaseEngine_x64 2016 installed as above in (1).
Using AnyCPU in the visual studio build settings failed in (1). Setting x64 is required. Maybe this is because AnyCPU means that Vstudio must see an x32 ACE.OLEDB.nn.0 provider at compile time.
The ACE.OLEDB.12.0 2016 x32 /passive engine would NOT install when it saw x64 applications around. (The ACE.OLEDB.12.0 2010 x32 /passive installer worked.)
CONCLUSIONS
To use x64 build settings, you need to have the 2016 x64 database engine AND the ACE.OLEDB.16.0 connection-string provider AND explicit x64 build settings to work with Office 365 in January of 2020. Using the /passive option makes installations easy. Credit to whoever posted that tip!
To use AnyCPU, I needed to have both the ACE.OLEDB.12.0 2010 x32 engine and the ACE.OLEDB.16.0 x64 engines installed. That way Vstudio could see both x32 and x64 engines at "AnyCPU" compile time. I could change the provider connection string to ACE.OLEDB.12.0 for x32 operation or to ACE.OLEDB.16.0 for x64 operation. Both worked fine.
To use x86 build settings, you need to have the 2010 x32 database engine AND the ACE.OLEDB.12.0 connection-string provider AND explicit x86 build settings to work with Office 365 x32 in January of 2020.
I have similar issue when we are reading Excel file.
History of the problem:
We recently migrated our application from 32-bit to 64-bit because of the memory requirement. For that we migrated our windows 7 from 32-bit to 64-bit. But still we installed 32-bit office on our machines.
because, of this we had this issue while importing Excel data into application.
Solution,
I downloaded 64-bit version of the http://www.microsoft.com/en-us/download/details.aspx?id=13255 and installed with argument as,
AccessDatabaseEngine_x64.exe /passive
Without any code change my issue get resolved.
Note:
On 64-bit OS and 64-bit office, my functionality was working fine without this fix. This fix is only required while our application is 64-bit running on 64-bit OS which is having 32-bit office installed on it.
I had this issue when attempting to import data from an excel file (xlsx) into a SQL Server DB using SSMS 2014.
The 2007 Office System Driver: Data Connectivity Components install did the trick for me.
I received this error when importing data from an Excel file into MS-SQL.
The provider was already installed (64-bit) and this surprised me why it didn't work.
So all I did was locate the Import/Export application used here i.e. the .EXE.
And I found it at
C:\Program Files\Microsoft SQL Server\130\DTS\Binn\DTSWizard.exe
I then ran the .exe directly to perform the data import. And it worked!
I followed the instructions set out by others; installing this patch, installing that patch as well as the Microsoft Access Database Engine 2010.
My issue was that I'm using the same library (linq2sql) in 2 sites on my machine; 1 works and 1 doesn't.
Eventually I found that I had to "enable 32 bit applications" in the advanced settings of the apppool for my non-working site.
Everything works fine now.
Just download & install the following Access DB engine (X86 or X64: as per your machine configuration) and see the magic :)
https://www.microsoft.com/en-us/download/confirmation.aspx?id=13255
If you get this error when trying to use ACE from an ASP.NET application, the most likely cause is that you have installed either one of the 32-bit versions. By default, IIS on a 64-bit operating system will run applications in a 64-bit worker process. 64-bit processes cannot load 32-bit DLLs. When a call is made to the ACE provider, the 64 bit process will attempt to locate a 64-bit DLL. If it doesn't exist, you get the error message that brought you here.
In this case you have two options. First, you can install the 2010 64-bit version. If you have the 2007 32-bit version installed, you can simply install the 2010 64-bit version alongside it. If you have the 32-bit version of 2010 installed, you need to uninstall it and download and install the 64-bit 2010 version instead. You cannot have both the 32- and 64-bit versions of the 2010 provider installed at the same time. If you are performing the installation on your development machine, you may also be constrained by the bit-ness of any existing Office installations.
The second option is to change the application pool in IIS to enable 32-bit applications. If you are using the full version of IIS, you can use the management tool to do this (Control Panel » Administrative Tools » Internet Information Services (IIS) Manager).
For more understanding please refer below link
for Visual Studio 2022 (and newer)
I had this error every time and it didn't help anything. VS2019 was the solution.
https://learn.microsoft.com/en-us/visualstudio/data-tools/accessing-data-in-visual-studio?view=vs-2022#data-providers
If you're using Visual Studio 2022 to connect to databases, you will
need to be aware that Visual Studio 2022 is a 64-bit process. This
means some of the data tools in Visual Studio will not be able to
connect to OLEDB or ODBC databases using 32-bit data providers.
If you need to maintain 32-bit applications that connect to OLEDB or
ODBC databases, you will still be able to build and run the
application with Visual Studio 2022. However, if you need to use any
of the Visual Studio Data Tools such as Server Explorer, Data Source
Wizard, or the DataSet Designer, you will need to use an earlier
version of Visual Studio that is still a 32-bit process. The last
version of Visual Studio that was a 32-bit process was Visual Studio
2019.
also can try these steps
In the SQL Server,
1.Open one data base
2.Clic in the option 'Server Obtect'
3.Clic in 'Linked Servers'
4.Clic in 'Providers'
5.Clic Rigth in 'Microsoft.ACE.OLEDB.12.0'
6.Uncheck all the options and close
I had the same issue but in this case microsoft-ace-oledb-12-0-provider was already installed on my machine and working fine for other application developed.
The difference between those application and the one with I had the problem was the Old Applications were running on "Local IIS" whereas the one with error was on "IIS Express(running from Visual Studio").
So what I did was-
Right Click on Project Name.
Go to Properties
Go to Web Tab on the right.
Under Servers select Local IIS and click on Create Virtual Directory button.
Run the application again and it worked.
I had Microsoft Access Database Engine 2010 Redistributable already installed on my machine but was still receiving the Microsoft ACE OLEDB Provider error.
Then I recalled that I had upgraded to Office 2016 recently, so, may be I should try reinstalling Microsoft Access Database Engine 2010 Redistributable. And that fixed the problem on my machine.
So, if you have upgraded to different version of MS Office or even repaired/reinstalled your MS Office then try reinstalling Microsoft Access Database Engine 2010 Redistributable before wasting time with finding other fixes. Good luck!
1.) Verify your connection string with ConnectionStrings.com.
2.) Make sure you have the correct database engine installed. These were the two database engines that helped me.
Microsoft Access Database Engine 2010 Redistributable
2007 Office System Driver: Data Connectivity Components
3.) There could be an issue with your build target platform being "Any CPU", it may need to be "X86" (Properties, Build, Platform Target).
I have a small windows forms application created in Visual Studio 2012 that uses ReportViewer version 11.0.0.0.
The application target framework is .NET 4.0 and its deployment method is ClickOnce
On my PC it installs but on client machines, intallation fails with error
the application requires that assembly microsoft.reportviewer.processingObjectModel version 11.0.0.0 be installed in the global assembly cache first.
On the client machines, i have installed
.NET 4.0
ReportViewer 2010
Microsoft Report Viewer 2012 Runtime CTP
SQLSYSCLRTYPES.msi
in the project application files settings, i have set microsoft.reportviewer.processingObjectModel publish status to Include(Auto), in the references i have also set its Copy Local property to True.
what am i missing?
I have even followed the instructions here http://msdn.microsoft.com/en-us/library/ms251723.aspx
Here is (arguably) the best way to deal with this issue... without downloading or installing any extras. This worked with Visual Studio 2012 (Ultimate)
Goto the main project within your solution(default/statup project)
Right Click and Click Properties / Select "Your Project">> Project>> Properties
Click on "Publish" Tab to see publishing options
Goto "Install Mode and Settings">> Click "Application Files" and Dialog opens
Go down and look for the items set with "Publish Status" > Prerequisite
You will find ReportViewer and Several Other Files set to Prerequisite
Change all the Publish Statuses to "Include" in the drop down
I know you only need the ReportViewer Only but this will eliminate other potential problems I came across
Now all the required files will be added to your installation setup good to go!
For interest, you can change include a desktop icon under "Install Mode and Settings">>Options>Mainfests>Create Desktop Short Cut
you are missing the ProcessingObjectModel.dll file find the version 11.0.0.0 in gac assembly C:\windows\assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel and add it to bin dir.
We had the same issue, but the thing is, its automatically adding it to the references (microsoft.reportviewer.processingObjectModel), if u EXCLUDE it from the publishing properties(properties->publish->application files), It might fix it.
A better option would be to install the Microsoft Report Viewer 2010 SP1 Redistributable Package at:
http://www.microsoft.com/en-us/download/details.aspx?id=6610
Your users will need to have this package installed as well. If you just copy and paste a MS DLL, you'll have to redeploy it every time you upgrade your application.
If you are using WinForms, to me it seems pointless to worry about installing this DLL in the GAC when it's being used for a report viewer that is deployed via click-once. This isn't a big file and you're probably using it as a report viewer control on a form, nothing more. One possible solution is to do the following:
In Visual Studio, go to the reference in your project for the assembly Microsoft.ReportViewer.ProcessingObjectModeland locate the file path to the folder for that assembly. Mine was version 12 and so my file path was C:\windows\assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel\12.0.0.0__89845dcd8080cc91
Copy the file path of the folder the assembly is in and remove the reference from your project (right click the reference and select "Remove").
Win + R to get a 'Run' prompt. Paste that folder path in there and execute to jump right into the folder of that DLL.
Find the DLL, it should be the only file in that folder, and copy it to your Visual Studio project folder. You shouldn't care about 100kb of extra space on your drive consumed, and I don't think this DLL is one you'll need to update.
Back in Visual Studio, right click References, Add Reference, and browse for that DLL in your project folder. After adding the reference, make sure that the Copy Local property is set to true.
Clean and rebuild, test the application on your local computer, than Deploy your ClickOnce again.
Now when users install your application with ClickOnce, the reference will not refer to the GAC at all and there won't be any need to rely on the prerequisite check/installation process for this DLL because you have included it directly in your published application.
It depends on the setup type you are using but basically, it means the required library is missing from your server or computer. To enable the application to download from the server (In a client-server architecture), you need to include the file(s) in the project.
Go to your application option and locate the "Publish" tab
Click on "Application files"
In the ensuing dialog, select to include all the libraries you want included (or that are required to run your application on the client machine and click "Ok")
Build your application and then publish to the server.
I hope this works for you, it worked for me in Visual Studio 2010 Professional
In case of Windows 10 it won't work installing Microsoft Report Viewer 2010 SP1 as describe by user1236560. First you need to install Prerequisites for SQL Server Management Objects (SQLSysClrTypes.msi) need to choose between x86 and x64 depending on your hardware. You could find it on: http://origin.www.ms.akadns.net/downloads/en/details.aspx?FamilyID=16BC778C-357B-46E9-8356-D575903AC831
After that you need to install MICROSOFT® REPORT VIEWER 2012 RUNTIME that you could find on: https://www.microsoft.com/en-us/download/details.aspx?id=35747
Both of this package will have to be installed.
I encountered this error
System Update Required
Unable to install or run the application. The application requires that assembly
Microsoft.ReportViewer.ProcessingObjectModel Version 11.0.0.0 be installed in the Global Assembly Cache (GAC) first.
Please contact your system administrator.
this error popped out when installing an application made from Visual Studio
meaning I am one of the client
I have Visual Studio 2015 and a Microsoft SQL Server 2014 and didn't know about Crystal Reports and other related stuff to it. I do check the version of my .NET Framework which is version 4.6.2.
I have several extension files and distributable files downloaded and yet doesn't solve my problem.
I do not know if I solve the problem generally but I do become successful in installing the application
so I downloaded and installed the ff:
SAP Crystal Report for Visual Studio 2015(latest, just to make sure)
Microsoft System CLR Types for Microsoft SQL Server 2012
Microsoft Report Viewer 2012 Runtime.
the problem took me about 2 days to trouble shoot, Be careful on downloading and installing extension files and distributed files cause it will munch some space too.
The Best answer is:
