I am having third party dll called "xx.DLL",i included in my web project, i copied and paste the project into IIS wweroot folder.I am using IIS7.5,then when i try to browse my application, i am getting the following error "Could not load file or assembly 'xx.DLL' or one of its dependencies. The specified module could not be found."
Its working fine in local PC's, but when i try to host and browse in Windows Server 2008 R2 Enterprise Service Pack 1(64-bit OperationSystem) i am getting the following error.
I don't know what is the problem ?
Any ideas?

I have a WCF service which references LevelDB-sharp (https://github.com/meebey/leveldb-sharp) which in turn references (DllImport) leveldb.dll.
Everything runs perfectly on my development machine, but as soon as I deploy it to live, I get the error message
The server encountered an error processing the request. The exception
message is 'Unable to load DLL 'leveldb.dll': The specified module
could not be found. (Exception from HRESULT: 0x8007007E)
I've tried putting the dll in the web service directory, the bin subdirectory, system32 and also system32\inertsrv and keep getting the same error.
I've also tried hard coding a path into the DllImport calls.
What am I missing?
DllImport calls does not follow the normal .net probing path ,it will look through windows PAth variable paths.
Since you have already tried to put the dll to inetsrv and system32,I guess your IIS webapplication pool may be running on 32bit mode.Are you running your application pool in 32 bit mode ?
If so, Please try and put the leveldb.dll in your syswow64 folder or
C:\Windows\SysWOW64\inetsrv folder
I wrote a simple VB.NET application which works fine on the development machine.
However on another machine, even though the .NET Framework is installed, it crashes on startup with System.InvalidOperationException.
There seems to be a problem with it finding the Visual Basic assemblies.
Here is one of the fails (I replaced sensitive information with three dots):
*** Assembly Binder Log Entry (16/06/2013 # 15:45:12) ***
The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

It isn't that clear why PowerPacks is missing, the .NET 4 Client Profile could be an issue. There have been multiple versions of PowerPacks around and the version numbering got to be a mess. On my machine, that same version is reported as v2.0.50727, even though it is stored in the GAC as version 10.0
Best thing to do is to go back to your project. Click the "Show All Files" icon on the toolbar in the Solution Explorer window. That now shows the References node. Expand it and select the PowerPacks reference. In the Properties window, change the Copy Local property to True.
Rebuild and your build directory now will have a copy of the DLL. Copy it along with the EXE onto the target machine.
Here is the URL to download Microsoft Visual Basic Power Packs 10.0

Apparently, it seems to be a problem with the "PowerPacks"; these are additional controls to the ones given by default in Visual Studio (in the form design part, under "Toolbox"). If you install the required package on the target computer, everything should be fine.
I had this problem in the past and my recommendation is not relying on these elements: they include nice-to-have features (in my case, it was an elliptic shape) but might be replaced with a bit of work and simpler objects. If you want to sell your program to a more or less wide audience, relying on this might become a problem: this package is not installed by default on virtually any computer and thus you would have to ask your clients to go ahead with the installation. Locating these specific controls is straightforward: on the "Toolbox" they should be listed under "PowerPacks" or similar.
After reading the Hans Passant's comment, I do recall that a .dll file has to be put in the same directory than the executable, but I am under the impression that the PowerPacks package from the provided link has to be installed anyway (at least, on computers not having Visual Studio).
I was upgrading Visual Studio from Visual Studio 2013 to Visual Studio 2015 on a new Windows 10 machine. In doing so I copied my Projects folder from a Windows 7 machine to the same path on the Windows 10 machine.
When I opened a project which used MS.VB.PowerPacks.VS I was informed the file could not be found. I downloaded the newest install for MS.VB.PowerPacks.VS Version 12.0.0.0. Visual Studio 2015 blanked out my form pages which used the PrintForm and informed me:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.VisualBasic.PowerPacks.VS, Version 10.0.0.0.
I changed the reference to vcersion 12.0.0.0, but it was still not recognized.
My fix: I copied the the C:\Program Files(x86)\Reference Assemblies\Microsoft\VBPowerPacks\v10.0 folder from my Windows 7 machine to my Windows 10 machine, and then removed the v12.0.0.0 reference and added the v10.0.0.0 reference to the program. I then exited the project and opened it again, and all was well, the forms were displayed in their original beauty.
I am currently working on my product installation in Windows XP 64-bit machine. I am trying to register my COM modules as part of installation. I am doing this by adding an entry in 'RunOnce' (registry) key to launch a bat file and registration is done from that bat file.
All my COM dlls are registered correctly but two of the COM servers (.exe) showing error that it failed to load one of its dependency dll. But the same dll is statically linked with another COM server and this server registered successfully !
And surprisingly running the same bat file directly(double clicking on it) doesn't generate any errors and its works fine for all assemblies!. I have checked this in couple of my test machines only of the machines showing this behavior. Unfortunately that't the customer tool machine.
Its not dependency dll not available issue. Because after registering all files by directly running the bat file, I could reproduce this again by adding a key in RunOnce manually and restarting the machine.
Additional info, I am accessing this machine remotely via logmein.
Exact error message: "This application has failed to start because XXX.dll was not found. Re-installing the application may fix this problem".
This XXX.dll is not available in the same path but its in another folder and its path is available in path variable.
bat file content is;
"C:\WINDOWS\system32\regsvr32.exe" RemoteControlHandler.dll
"C:\WINDOWS\system32\regsvr32.exe" ProcPgmHandler.dll
"C:\WINDOWS\system32\regsvr32.exe" GEM300Handler.dll
"C:\WINDOWS\system32\regsvr32.exe" ICEScreenAdapter.ocx
HIB.exe /regserver //Throws error
JobManager.exe /regserver
Cim300Adapter.exe /regserver
GemEquipmentCtrl.exe /regserver //Throws error
Hope this information is enough for experts, feel free to ask if you need any additional information.

I am trying to retrieve Build Projects related information from my CruiseControl server through command line using cccmd.exe and passing the url and project name as command line arguments. The problem is when I am trying to use API's exposed by Cruise Control Service like
client.GetArtifactDirectory(project.Name);
client.GetLatestBuildName(project.Name);
I am getting the exception "The project does not exists on the CCNet Server" for my local CCNet Server.
For my production build server, I am getting the exception "Key cannot be null".
Finally found the solution, had to copy the folders and foldername.state files that are created during project build process to the directory from where ccservice.exe was running.
I am currently trying to build a Resource DLL on on Windows Server 2003 and 2008. I am currently working with the Resource DLL code samples supplied with the Windows SDKs, and I can't get them to work.
On Windows Server 2008 I succeeded compiling the Windows 7 SDK ClipBook Server sample, but couldn't get it to properly work in the cluster. When I insert the resource as a resource type to the cluster using "cluster restype /create /dll" it works, but the resource is listed with an unknown type instead of a ClipBook Server type, as I think it should have as it is the type defined in the Resource DLL's code.
I also succeed in creating a resource of that type, but I can never get it to go Online. I always get the error:
System error 5079 has occurred (0x000013d7).
The specified node does not support a resource of this type. This may be due to version inconsistencies or due to the absence of the resource DLL on this node.
And this is despite the fact that the resource is located on all the nodes in the cluster including the one I try to start the resource on.
On Windows Server 2003, I'm working with the Platform SDK version 5.2, and I can't even get the ClipBook Server Resource DLL code sample to compile. I always get MIDL1001 Error saying that it cannot open the file cluscfgserver.idl. I added the path of the file's location to the include path of the project. That didn't work. When I tried to hard-code the path of the file, I got several linker errors when trying to link with this file.
If anyone knows anything about any of these problems, I would appreciate any input.
Those examples are old and busted. Here are a few things I had to go through to get the similar "File Share Sample" to work:
Convert the project to x64 (supposedly 32 bit resources still work, but I haven't been able to verify that)
Add the module definition file (.def) to the linker input property page so that the Startup function is exposed
There were several spots in code where CompareString is used to check the resource type name and 0 is expected on success, but it actually returns CSTR_EQUAL (3).
This is probably why you get the "(Unknown Type)" name.
To register the resource extension, cluster.exe won't accept spaces in the dll name, so in my case I had to use cluster /REGADMINEXT:'FILESH~2.dll'
Only the Property Sheet extension interface is supported, everything else (context menu, wizards) has been removed as of Server 2008
Check the extension DLL stdafx.cpp sources for the Resource Type "ClipBook Server". It should be "ClipBook Server Sample": const WCHAR g_wszResourceTypeNames[] = L"ClipBook Server Sample\0"
