Solution 1

Look at your code, do you have [System.STAThread] or just [STAThread] before your entry point (usually Main)?

If not, add it.

If this does not solve your problem, show your code, try to catch exception and provide exception dump. Don't forget to indicate code line(s) where exception is thrown.
