Using a dual boot machine

You must use different serial numbers when you install PC-cillin into dual boot machine.

If you installed both Windows 98 and Windows 2000 using dual boot machine and want to use PC-cillin for your machine, you have to buy 2 license of PC-cillin. In this case, you have to repeat the same installation processes for each OS. You must perform on-line registration once for each OS. Since you use different serial number, you will get different license key for each OS. Please keep registration date.

License key is issued using your serial number and OS information. If you get 2 license keys using different OSs, one license key may be invalid.
