I have an issue accessing the EngineeringBase.Interop.dll with an external Application (in C#).
The other Application can be run as Administrator (with UAC prompt) for other reasons, and in those cases the Access fails if Engineering Base is already running (not elevated):

Error : Retrieving the COM class factory for component with CLSID {101E0584-E1D8-11D2-B72E-00805F52B443} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

It works when both Processes are running elevated (or both not elevated) so I believe it is not related to EB but probably more a general COM limitation I guess?
If that is true my question is just how can I detect this situation from my Code?
