    shield from X-WinPro's program group.
 2. Run/extract this license.exe to same directory where
    you have stored X-WinPro's installation files
    (default is c:\xinstall). If you have deleted
    c:\xinstall directory and xwp32.exe or xwp16.exe

    files which come with license.exe

    you just stored X-WinPro's installation files    (default is c:\xinstall).
