I’m trying to install Norton 2009 in a Vista 64 bit machine. There is a message that the installation has detected another Norton product and then proceeds to uninstall it. Then after a short time, I’m told that the machine must reboot to continue the installation. But after the reboot the whole thing starts all over again - the detecting, clearing, and need to reboot. I’ve found out from troubleshooting here at Norton the trouble is a temp file is not clearing on the reboot, and I downloaded a tool to correct it. But the tool says there is nothing wrong found. In fact I don’t have any previous verson of Norton AV anymore on my machine! I did a regedit and deleted all entries containing Norton - but no help. I tried a search here in the forum and nothing came up.
