ok i'm not sure if this is the right section to put this in but i have two computers one running win me the other running winxp pro my question is i have norton system works 2001 on the pc with win me can i use the same program version on win xp pro?according to the documentation on the cd it says that win xp is covered by it but i'm not sure.i had nortons anti-virus corporate edition on my win xp computer but it stopped working and all the downloaded updates would no longer install(kept coming up with error 16 bit file cannot run on this system)even though i've updated every night to get the latest definitions.winxp was in ntfs files when installed not 32 bit.unfortunately my nortons disk is damaged and i cannot replace it so i'm stuck with an earler version.to tide me over i tempoarily installed kaspersky and it caused me nothing but problems.where nortons had said there were no viruses this rotten thing kept finding stuff and i refused to ignore,disinfect or quarantine so my only option was to delete.everything seemed fine till about twelve hours later when the pc got really slow and took forever to load anything so irestarted the pc only to find that it was impossible to get anything to open without it sitting and thinking about it for half an hour at a time.i've come to the conclusion that the files kaspersky deleted were system files and my pc tech agrees.i will be reinstalling win xp but want to know if i can use nortons systemworks 2001 safely with xp?
