Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'.

  • Article

While launching Visual Studio 2012/2010 IDE, you might receive the below error message or VS IDE may just crash without any error message. I launched the devenv.exe in the debugger (https://msdn.microsoft.com/en-us/windows/hardware/gg463009) and took a crash dump (https://support.microsoft.com/kb/286350). You can also run the following command: cscript adplus.vbs -crash –sc "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe"

After debugging I found the below Call Stack and exception:

The exception seems to indicate the crash was caused due to an interface not being found.  This indicates that something's wrong with proxy/stubs on the machine. At least IServiceProvider is failing. IE is usually the owner of the IServiceProvider proxy.
From the dump, it showed devenv.exe process crashed shortly after loading:  C:\Windows\SysWOW64\actxprxy.dll and C:\Windows\System32\mssprxy.dll

The issue turned out to be broken registration for IServiceProvider. The proxy-stub CLSID was wrong (it was referring to actxprxy.dll instead of ieproxy.dll on Windows 7 x64). Registering ieproxy.dll from an elevated cmd prompt resolved the issue.  regsvr32 "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"  

On x86 systems,  regsvr32 "C:\Program Files\Internet Explorer\ieproxy.dll"
