So if the 32 bit installer will still be done, then what is going to stop installation on XP PRO SP3 ? ? I can understand if not all the components will work, but what about just the basic Antivirus portion without all the (mostly unused) bells & whistles ? ? For example: On my computers I only install: Behavior, File & Web Shields .... I just noticed we have a Program Update to: 18.7.2354 ... Time to download and update it.
