Prior to upgrading to XP I had Norton System Works 2001 (old now???) on my machine. It is not compatable with XP so it is sat on the shelf with the manual doing nothing. It is compatable with Win95 os2/Win98/ME/NT 4.0 Workstation & wIN 2000 Proffessional. If it is any good to you e.mail me your address and I will post it on (yellow envelope left of my name).
