    I am running a application on Windows 7.  It does not work and gives me the messages:
    Direct3D9: (ERROR) :Could not create exclusive mode mutex. exiting
    The thread 0x95C has exited with code -1073741502 (0xC0000142).

    I had download and installed the lasted directx 9c from microsoft website!
     VC++ 6 and sp6

    How can I do?

    Thanks for all!

    What version of the DirectX SDK are you using to create the program? If you are using VC++ 6, it would have to be a pretty old version. The latest SDK requires at least VS 2005.

    I suspect that the SDK version you are using has bugs or incompatibilities with Windows 7.

    Make sure you have the latest video drivers for the Windows 7 machine. The problem really sounds like a driver compatibility issue.

    Also, you need to throw away VC++ 6. That thing is awful (and unsupported). Get VC++ 2008 Express Edition (or VS 2008 if you have the money) and the latest version of the DirectX SDK.

    Beyond that, I can't really say for sure. Google didn't turn up a lot of help on the issue.
