I've now received my Acer Vista Upgrade disks and the instructions mention the need for updating Norton Security for Vista and gives the relevant Symantec web address.
What is not clear to me (from the instructions or the Symantec link) is whether the Norton Update needs to be done prior to attempting to install the express upgrade or whether there will be a prompt during the upgrade.
Any help would be appreciated as I'm well aware there could be problems and want to avoid any if at all possible.
they advise you to disable any av programs before upgrade as this can make vista unstable?! i removed nis with add remove, when vista is set up, you can either download vista version from control panel security or the link you already have. hope this makes sense
