Sorry if this is the wrong place to put this. Today I formatted my computer and when I try to install some programs, IE: IncrediMail and also my newly purchased Rollback RX, an error pops up, "the installer has encountered a problem and needs to close". now I have tried fresh installers for both programs and restarted my rig many times with no luck. Also my windows XP SP2 is up to date. The problem started last night when I installed a certain antivirus beta. More info available on request. Anyone have any ideas? I'm ready to throw this computer through the wall.
