    We have Web, windows products designed to worked on 32 bit OS. I am curious
    to know if those applications will work as it is on 64 bit OS.

    Our Microsoft Windows based desktop products are desiged using VC++, MFC,
    ATL, COM, VB
    Web based applications use ASP, ASP.NET, COM technology.

    Will these application run as it is without any major changes on 64 it OS.

    Any links and knowdge article will be helpful

    Cheers ! Thanks in advance

  2. 32-bit applications should run fine, assuming they don't depend on a system
    level driver. And assuming the installer you use is 32-bit, not 16-bit. Your
    web products will potentially not work with the 64-bit version of IE if they
    are dependent on 32-bit ActiveX components, etc. But they should work fine
    against 32-bit IE, which is the default browser.

    For links and kb articles, I strongly suggest that you google. There's a lot
    of information out there, including a fair amount on the MS site.
