试试这个，应该可以.

TCHAR lpszClientPath[500]= TEXT("c:\users\e\desktop\mspaint.exe");
if(!CreateProcess(NULL, lpszClientPath, NULL, NULL, FALSE,  NORMAL_PRIORITY_CLASS|CREATE_NEW_CONSOLE|CREATE_UNICODE_ENVIRONMENT,NULL, NULL, &si, &pi))
            {
    printf( "CreateProcess failed (%d).
", GetLastError() );
        return;
            }
...
