I have an AMD 2200+ with 512 MB RAM running Windows XP. I also use Norton Systemworks Pro 2004 and Norton Internet Security Pro 2004.
I simply installed SP2 "over" my present configuration. No problem.
Recently I had a hard disk issue. I decided to "crash" mysystem and reload all my software. I re-formatted my drive, installed XP, installed my motherboard drivers, then downloaded all Windows Updates, including(!) SP2, BEFORE installing Systemworks Pro 2004 and Internet Security Pro 2004.
BIG problems! Very eratic operation. Could not get either Systemworks or Internet Security to function.
I finally tried a different installation procedure: installing Systemworks and Internet Security BEFORE downloading the Windows Updates (including SP2)!
All works well. I'm just wondering if others have experienced this same issue. What a headache.
