C++ Program running on Windows 7 64-bit is a mess RRS feed

  • Question

  • Hi,

    I have an application that was developed with Microsoft Visual C++ .NET.  It runs successfully on Windows XP, Windows Vista and some versions of Windows 7.

    I have a new customer that is trying to use it on Windows 7 64-bit and it is a mess.  None of the controls are coming up on the screen properly and he is getting error messages when he tries to use some of the features.

    Can someone tell me what I need to do to get my C++ program to run properly on Windows 7 64-bit?

    TIA,

    Brad McMillan

    I think you will have to, at the very least, recompile it on a Windows 7 64-bit machine.

    More likely, you may also have to make a few changes, as per this article http://www.viva64.com/en/a/0010/

  • Hi Brad,


    If this program is developed by you, it is better to post this issue in MSDN forum for more help.

    If not, you need to contact the application provider about the compatibilityissue.
