I recently installed SQL Server 2008 Express on my Windows 7 Ultimate x64 home machine. I also have IIS 7.5 with PHP 5.3, and I was trying to connect to SQL via ADODB, but kept getting this error:
[Microsoft][ODBC Driver Manager] The specified DSN contains an
architecture mismatch between the Driver and Application
After doing a small amount of digging on the internet, I think this is because the SQL Server ODBC driver is meant for 32-bit operating systems, and mine's 64. First of all, am I correct? Is this the reason I'm running into trouble? Secondly, if so, how do I fix this? Are there any updated ODBC drivers that work with 64-bit operating systems? I looked but was unable to find any...
You're right in that it has to do with the bits.
Hope this helps:
--From MSDN --
To manage a data source that connects to a 32-bit driver under 64-bit
platform, use c:\windows\sysWOW64\odbcad32.exe. To manage a data
source that connects to a 64-bit driver, use
c:\windows\system32\odbcad32.exe. If you use the 64-bit odbcad32.exe
to configure or remove a DSN that connects to a 32-bit driver you will
receive this message.
I've been having the same problem trying to link a 64 bit SQL 2012 server to 'Sage Timberline' using Pervasive ODBC Client Interface.
I can set up the 32 bit DSN, but SQL Server keeps giving me the "architecture mismatch" error when trying to create a linked server using the 32 bit DSN.
I tried the C:\Windows\SysWOW64\odbcad32.exe to add the driver. But when I set up a linked server between MAS90 and SQL Server 2008 R2 I still get the architecture mismatch error. Just spoke to a guy from Sage and he says it won't work with 64-bit edition of Sql Server. The linked server works with MAS90 only if the edition of Sql Server is 32-bit.
I'm betting you are working with User DSNs.
Depending on your perspective, there's a "feature" or "bug" in the 64-bit Windows environment --
32-bit User DSNs show up in the 64-bit Administrator and when 64-bit client applications ask for all available DSNs -- even though the 32-bit DSNs cannot be used by the 64-bit client app and Adminstrator.
64-bit User DSNs show up in the 32-bit Administrator and when 32-bit client applications ask for all available DSNs -- even though the 64-bit DSNs cannot be used by the 32-bit client app and Adminstrator.
The error message you describe comes up anytime there's such a bitness mismatch between the DSN and the client trying to work with it.
Microsoft's recommendation is to name your User DSNs with _32 or _64, depending on the bitness of the driver on which they're based ... or stick with System DSNs.
There are 32-bit and 64-bit solutions for the connection you want. The bitness of your client application(s) -- IIS & PHP, in this case -- dictate the bitness of the solution you require.
if 32 bit application on 64 bit operating system (the application you are installed under [program files (X86)] use the following
C:\Windows\SysWOW64\odbcad32.exe
otherwise 64 bit application and 64 bit operating system use the following
C:\Windows\System32\odbcad32.exe
otherwise you will get a error like "Architectural mismatch"
Hope this will save someone's day :)
This worked for me:
Updated solution, make sure the IIS application is NOT set to 32-bit on x64 Windows. More info:

I want to create a linked server for connecting to excel file and i have used below address for doing that:
https://www.sqlshack.com/query-excel-data-using-sql-server-linked-servers/
After installing (accessdatabaseengine.exe) the provider has not been added to my provider in sql server.
When i wanted to install accessdatabaseengine_x64.exe i got error because office is 32 bit.
My office is 32 bit version and my sql server is 64 bit version. I do not have permit to re-install of my office and my sql server.
Please help how i can solve my problem.
Masoud,
Architecture versions have to match unfortunately so you would need to install 64-bit office to make that adaptor to work.
You could possibly use SSIS to a raw table and process that way but this depends on your workload and frequency of updates required.
My Problem is that I cannot connect to an SQL Server Express 2008 64bit Database via an Access Runtime 32bit, neither by Windows authentification nor by SQL auth.
On the Windows 2011 Small Business Server runs a Virtual machine with Windows 7 Prof. 32 bit. From this Windows I tested my Access App. using a (32bit) SQL Driver 11, which works fine.
The same Access App used from a 64 bit Windows 7 Prof. Client using a 64bit SQL Driver 11 fails with SQLState 08001 error.
The Thing which I do not understand is, that ODBC Connection test is successful, a data link (UDL) is successful, but not my Access App.
When starting the app, the first Thing is to run a stored procedure through a passthrougquery and grab data from a certain tbl in the SQL-Database. This SP brings the Connection error, but not an runtime error from Access (I removed even an error handler!).
So, how can I find the reason or any error in the Access app (if there is one)?
I am helpless as anything I know to test or to do I already tried out to make the app run. As I cannot even install the SQL Driver 11 in 32bit, it should not be a Driver related error.
Does anyone know a test-app, where I cannot only connect but retrieve data from an SQL-Database or any other tricks to check the Access to the database?
Thanks your help!
Access usually is installed as a 32bit Application. So on 64bit computers it will use the 32bit subsystem. On Windows 7 all the default shortcuts to the ODBC Data Source Administrator utility will lead to the 64bit version of it. Whatever you see or configure there is completely irrelevant, as your 32bit Access is not going to see it.
Solution:
You need to explicitely open the 32bit version of the ODBC Admin utility and configure the data source there.
To make sure you get the right version, use Windows Explorer and open this file: C:\WINDOWS\syswow64\odbcad32.exe
Well, what I found out meanwhile is, that the Connection Fails when trying to use a Connection like this "ODBC; DSN=MyDSN;....." but it works, when I make a Connection DNS-less, by connecting with "ODBC;DRIVER=SQL Server Native Client 11; SErver=myServer;....".
Maybe this is exactly that what you are talking aout. When I just use a DSN it takes the wrong bit Version.
So I will try this: delete the DSN I have, open odbcad32.exe and create the same DSN again.
If I understand you correct, then Win 7 provides the correct Driver and stores it in the DSN. Calling this DSN by Access would lead to the correct Settings.
Further Problem is, that my SSQL-Server instance is not at port 1434, and the SQL Server Native Client 11 Driver has no more Clientconfiguartion to set the static port. So I found a string solution for that "MyServer\Myinstance, 15999".
I hope that this port Setting will be accepted in the DSN, otherwise I really have to Change to DSN-less which is more complicated due to different Servers for the development and the production.
Thanks yr. reply.
I have a web server (Coldfusion) and 2 remote networks that have SQL servers. For both remote offices/networks I query for data every 10 minutes. It has been working for some time now. In one of the offices/networks, AT&T dumped our public static IP address. They assigned a new one and I have made the appropriate changes to the firewall. Now I can use the Windows ODBC manager and test the connection from the web server and it passes just fine. But, when I try to verify the Coldfusion data source, it fails, "timed out trying to establish connection".
ColdFusion 9 doesn't use the Windows ODBC drivers; it uses JDBC drivers. Changing the Windows ODBC drivers and testing them will have no affect on your CF sites.
Update your DSNs in ColdFusion Administrator. Remember, you access your CFAdmin via:
http://localhost/CFIDE/Administrator
unless you've specifically changed it during install. Obviously, replace "localhost" with the server's IP or hostname if it is externally hosted.
ADDENDUM
The exception to the above rule is when you are using the ODBC-JDBC Bridge (CF DSN type = "ODBC Socket"), in which case, you need to verify that:
a) The Windows ODBC Driver (System) is set up, tested, and working, and
b) The CF DSN is pointing to the correct Windows ODBC Driver.
If you are using Windows Server 2008 64-bit, then you may be having trouble with your ODBC because you could be looking at the 64-bit connection list, rather than the 32-bit. In this case, you will have to open up c:\windows\syswow64\odbcinst.exe to access the 32-bit ODBC manager (yes, you read that right; the 32-bit version is under a folder named syswow64).
It sounds to me like there is a good chance that the driver settings you need to update are there, instead of those found registered under the 64-bit ODBC manager (which is the default ODBC manager under control panel). You may have actually had duplicate ODBC entries, one under the 64-bit list and one under the 32-bit list, and this could be the source of the confusion - CF could be using the 32-bit version. In any case - this would be a good thing to check.
Is there a good thorough authoritative reference that discusses interoperability between 32-bit and 64-bit processes? Based on googling I have deduced that:
A 32-bit DLL can only reside in a 32-bit process, and a 64-bit DLL only in a 64-bit process.
32 and 64-bit processes can only communicate using loosely coupled message systems, such as network communications, which means they can communicate using COM/DCOM.
32 and 64-bit COM components have different registry entries. A component is typically only registered in one of the two and typically only seen in one of the two worlds.
A 32-bit process can only create something registered as a 64-bit COM component if it uses CoCreateInstance with the 64-bit invocation flag, or (and I am guessing on this one, is it possible?) if the 64-bit component is somehow registered in the 32-bit registry but under the hood is still created as an out of process 64-bit process, or if there is a 32-bit shell COM component which creates the 64-bit component and then redirects calls to it?
This suggests that:
1. A 32-bit application can not use GetObject to get hold of a 64-bit version of Excel that is running? Or can it? How is the running object table (ROT) impacted by 32 versus 64-bit issue? Can a 32-bit process create an instance of Excel if only a 64-bit version of Office is installed? I would think the answer would be "no" unless the 32-bit process uses the 64-bit flag in its CoCreateInstance call, or if Excel somehow registered itself in the 32-bit world as well?
Does Microsoft automatically do anything like having CoCreateInstance from a 32-bit process check the 64-bit registry and try to create an out of process 64-bit component if there is none registered in the 32-bit registry? I have seen some release notes from 64-bit Office where Microsoft warns about access from 32-bit applications to 64-bit Excel not working, yet I know of one instance where it seemed to just work.
Is there a good technical factual reference for this?
It is explained quite well in the MSDN Library docs for CLSCTX. Lots of rules, the default behavior is:
If neither the client nor the server
specifies a preference, then:
If the computer that hosts the server is running Windows XP or
Windows Server 2003 without Service
Pack 1 (SP1) or later installed, then
COM will prefer a 64-bit version of
the server if available; otherwise it
will activate a 32-bit version of the
server.
If the computer that hosts the server is running Windows Server 2003
with SP1 or later installed, then COM
will try to match the server
architecture to the client
architecture. In other words, for a
32-bit client, COM will activate a
32-bit server if available; otherwise
it will activate a 64-bit version of
the server. For a 64-bit client, COM
will activate a 64-bit server if
available; otherwise it will activate
a 32-bit server.
Check the MSDN article if you want to override this behavior.
I have installed Oracle Client 10g 32 bit and ODAC 11g R2 on my Windows 7 machine, but I cannot see any Oracle Providers in MS ODBC Administration or when I try to created a linked server to Oralce in SQL Server Management Studio or in Visual Studio 2010. Can anyone please help me out as what to do? I can connect to Oracle server through SQLPlus but get errors when connecting through VS 2010 using MS providers for Oracle.
Please help!
When you installed the Oracle Client, did you also install the ODBC driver? IOW, did you do a custom install and add in the ODBC driver? Unless you do a full client install the ODBC drivers are not installed.
You're not specifying if your windows 7 installation is 32 or 64 bit.
If it's 32 bit then see the previous answer, restart Oracle installer and check that ODBC is selected.
If it's 64 bit I advise you to install both the Oracle client in 32 bit (as you did) and also the Oracle 11 client in 64 bit, so that you can use the proper library.
In any case I still haven't found a proper way to perform Oracle installation on Windows 7 (64 bit) that works for every client and tool combination, good luck.
I struggled with this for a while too, best solution I found was here:
