    I have a MFC Ribbon application that I developed on 32bit system. I have statically linked to MFC. My question is whether this application will run fine on 64bit XP/Vista?

      It will if you have all the necessary dependencies. 32-bit apps run in the WOW64 shell under 64-bit OSs

      «_Superman_» I love work. It gives me something to do between weekends.

          If the app runs fine on a 32-bit OS, it is guaranteed to run fine as it is (most of the time) on a 64-bit OS. The app. would still be running as a 32-bit application.

            Unfortunately my application crashes on 64 bit OS. Guess I'll have to debug on a 64 bit to find the problem. Anyways thanks for the replies.
