    char lpszPath[MAX_PATH] = {0};
    SHGetSpecialFolderPath( NULL, lpszPath, CSIDL_PROGRAM_FILES, 0);
    char installpath[256];
    sprintf(installpath, "%s\\Game\\Mario.exe", lpszPath);
    
    
    HKEY hKey2;

    Use strcpy() if you want to make a copy of a C-Style string.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    >> I tried strcpy() I get errors.

    then post your code and the errors.
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    I would think you would get warnings with strcpy(), not errors. Unless you have good reason, don't use an unsigned char array. If you need to, use strlen() and memcpy().

    As a side note, since we're in C++ land, you can always use strings.
