Unable to cast COM objects

I received this error when I clicked "Add Solution to Fortress" in VS2008. I'm also running on Windows Server 2003 64bit and re-registering actxprxy.dll which was the fix for others didn't fix the issue on Fortress 1.1.0. I have Visual Studio, SourceGear, and Sql Server 2005 all on different VMs.

Code: Select all

Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{6D5140C1-7436-11CE-8034-00AA006009FA}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Is there something else that might fix this issue?

Thanks,
John

Try running %windir%\syswow64\regsvr32.exe to register the dll.

Thanks! That worked.

I thought since it was a 32bit app I needed to run Windows\System32\RegSvr32 and would only run Windows\SysWow64\RegSvr32 for a 64 bit app.

I am having the same problem. What dll do I need to register? On the client or on the server?

actxprxy.dll on the client.

This thread has more information.

Newer versions of Vault should make sure this dll is properly registered. What version are you running?
