    64bit Program Cannot Start(0xc00007b Error)


    I am using Delphi XE3 to build a 64bit Program under 32bit system. However, whenever I run the 64bit program
    in a 64bit virtual machine, I will always get an error message “The application was unable to start correctly (0xc000007b).”.
    I try to use Remote Debugger to debug the program. However, even when I starting the debug by clicking F8,
    I will still get the error message. So I cannot even access the first source line of the program before the error occurs.
    In such a case, how to debug such a program and find out the actual reason that cause the error?

    The error is coming from Windows, not your application.

    Google suggests that you need to (re)install the x64 versions of whatever dependencies you're using - .NET Framework, DirectX, etc.
