    For some reason I get a negative value from this function on some computers.
    I really can not switch to another function such as GetTickCount because I have a big application which uses QueryPerformanceFrequency all over.

    I already tried to do
    QueryPerformanceFrequency(&ticksPerSecond); //freq in [counts per second]
    unsigned __int64 Ufreq = ticksPerSecond.QuadPart;

    It doesn't help...

    Any suggestions?

    I can't seem to find a solution on the web even though this problem occurs on more than one computer...And this function is quite an important one I assume...

    Thank you

    U can try considering the value returned as hex value and proceed with normal calculations after that.
