Norton Antivirus 2005 Upgrade problem with Windows ME OS.
Posted on 2004-10-04
I recently purchased Norton Antivirus 2005 Upgrade via dowmload from Norton Antivirus 2004. I cannot fully install 2005 because the program gives me a "Trial Period has Expired" warning and gives the options of purchasing the software (which I already did) or clicking the radio button that i have already purchased the software and to activate it by typing in the activation key into a box below. I copy and paste my key from the confirmation email from Symantec for the 2005 upgrade into the box and I get "there is already another instance of config sys running". then my amount of RAM drops so low that nothing works and I have to restart. I've uninstalled the Antivirus and am running at 72-79% free on "performance". I read at the Symantec help page that it may be due to haveing a virus or worm already in the system that is preventing the upgrade. I don't know what else to do. Thanks in advance.
