Hi,

I have developed a C# .NET v2.0 application that is using a third party dll
storing a COM ( afaik dll is compiled with FoxPro if it does matter ).
Everything is OK on x32 OS but when running on x64 Win 2003, application
throws

"Retrieving the COM class factory for component with CLSID {GUID HERE}
failed due to the following error: 80040154."

exception ( dll is registered with regsvr32 and I can find its entry in
registry - its InprocsServer32 is pointing to the correct dll )

I have found the following solution to the problem - to rebuild .NET app
with Project platform set to "x86"

http://forums.asp.net/t/1119052.aspx

After rebuild'ing I haven't got the exc mentioned above, but the application
does not execute correctly anyway.
Just after a COM is tried to be instantiated, an application waits about 30
seconds and then throws

" Exception Message: The server threw an exception. (Exception from HRESULT:
0x80010105 (RPC_E_SERVERFAULT))."

on the first try to invoke COM method.

Does anybody have an idea what could be the problem ?

Thanks for Your help!
