Hi All,

We are testing 32 bit windows application(developed in c#) in 64 bit windows XP.
This application uses COM wrapper(generated using tlbimp) and resouce file

when we run this application on 64 bit OS, application crashed we get following error

[System.TypeInitializationException] = {"The type initializer for 'CampaignRoleEditor.Classes.clsCommon' threw an exception."}
[System.Runtime.InteropServices.COMException] = {"Retrieving the COM class factory for component with CLSID {A7F45818-ED1F-4FB1-8808-DE609C5BA543} failed due to the following error: 80040154."}

Thanks in advance....

Reason for Edit: Moved to the Programming and Design forum.

The research I have done suggests that the DLL file that is associated with that CLSID has not been registered properly or it is a problem specific to x64 operating systems because your program has not been built in 32-bit mode. From what I read, if it is a .NET program it will have a 64-bit mode enabled and this is what is messing things up. You need to force the program to build in a 32-bit only mode. It will run in 32-bit mode even on a 64-bit operating system. So, try setting your Target CPU to x86 instead of AnyCPU. It is in the project's properties.
