InteropServices.COMException : Retrieving the COM class factory ... failed

AdrianSpear

Hi,

VS 2010 Professional
NUnit (2.5.10.11092)
Resharper (5.1.1753.4)

I have an NUnit test which creates a connection to a worksite as a basic integration test as follows:
IManDMS manDms = new ManDMS();

When the unit test is run in the NUnit Gui it runs perfectly but if I try running it in Visual Studio under Resharper Test Runner or in a Microsoft Test Class I get the following exception:

System.Runtime.InteropServices.COMException : Retrieving the COM class factory for component with CLSID {FDD9199A-1BB4-4433-B9E1-D550D3118676} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I checked the registry and the component with the CLSID above is not registered however I don't then understand why the NUnit Gui can succeed in that case?

Any help appreciated. Thanks.

Are you running on a 64bit platform? Is so, have you tried compiling your program as x86? I believe the iManage COM classes only support 32bit mode.
