    Exclamation Help! Access violation error in C++

    Hi everyone! I'm trying to enumerate registry keys:
    Code:
    LONG i;
    HKEY root; 
    DWORD retCode; 
    DWORD dwIndex=0;
    CHAR achKey[MAX_PATH];
    const TCHAR szRegRoot[] = _T("Software\\Microsoft\\Office"); 
    
    retCode=RegOpenKeyEx(HKEY_CURRENT_USER, szRegRoot, 0, KEY_READ, &root); 
    
    for (i = 0, retCode = ERROR_SUCCESS; retCode == ERROR_SUCCESS; i++) 
    {    retCode = RegEnumKeyEx(root, 
                         i, 
                         achKey, 
                         (ULONG *)MAX_PATH, 
                         NULL, 
                         NULL, 
                         NULL, 
                         NULL); 
    }
    When I about to execute RegEnumKeyEx(...) I got the error:
    First-chance exception in p5.exe (ADVAPI32.DLL): 0xC0000005: Access Violation.
    Enviroment: Win2K, VC++6.0.
    Thanks!
