VS2010 pro not able to start Moles host

Question

We are using Moles framework (0.94.5) to write unit test cases but not able to either debug or run the test cases.

System: Win7 64bit

Moles: 0.94.5 64bit with VS 2010 pro

The solution build successfully. But while trying to run test cases we are getting the following error.

{
Error
9/6/2013 3:35:32 PM

System.InvalidOperationException  : Could not start Moles host. Please review the Test Run Errors for more information.   //error

   at Microsoft.Moles.VsHost.Agent.MolesAgentAdapter.Run(ITestElement testElement, ITestContext testContext)  //error 
U0319VM2184

We also followed the fuslogvw to identify if there is any error during assembly loading. It gave two errors for Moles saying

The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

Assembly manager loaded from:  C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll

WRN: No matching native image found.

We checked the configurations and everything seems ok. On one of the blog it was mentioned to remove the .exe.config file from privateassemblies folder under VS2010 IDE folder. But could not get it working.

After following the above the error we got is moles looking for the project dll in a different drive from where project is located.

after we uninstalled moles restarted and installed moles restarted the machine but to no avail.

Could not find the right category under which to post this.

Thanks

+1 for research already done. It's appreciated and will get you far here.

I can add the following: You have a 64 bit machine and 64 bit moles. Are the tests you are running also 64 bit? If they are, the following solved this for me. If not, try it anyway.

1. Edit your test settings. IN VS2010, go to Test -> Edit Test Settings. Choose "Hosts" from the left side menu.
2. Select the option "Run tests in 64 bit process on 64 bit machine".
3. Save
4. Now open the AssemblyInfo.cs file in your test project.
5. At the bottom of the file, add the following line [assembly: MolesAssemblySettings(Bitness = MolesBitness.x64)]
6. Resolve any references.

That was all I needed.
