xxxx.exe encountered a problem and needs to close Windows error When I run my Qt app on Windows XP



  • Hi,
    I am building and successfully running my Qt app on windows7 and windows8 but face the following error when I try to run it on windows XP.

    XXX.exe has encountered a problem and needs to close. We are sorry for the inconvenience.

    The funny thing is that all worked just fine a few days ago and my previous builds are having no problem running. Think something I haven't found yet changed in my build environment. Tried to recopy the necessary dlls and runtime libraries but still no effect.Some threads suggested deleting the app data folder relating to my application but can't find anyting relating to the application.

    NOTE:My build environment is Window7 ,Qt 4.8.1 ,vc 2008.and I my system got updated last night suggesting that something might have changed.

    Any help will be appreciated.

    [quote]I am building and successfully running my Qt app on windows7 and windows8 but face the following error when I try to run it on windows XP.[/quote]I've found that compiling on Windows 7 and transferring the .exe back to Windows XP is shaky. Your program might get linked to features that aren't available on XP.

    Compiling on XP is probably the simplest solution.
