the bd installer gives me the error "A newer version of Bitdefender has been detected" and wont install, and YES i have run the bd uninstall tool, it reports every task as "not found." I have manually scoured my files and even registry to no avail, all i've noticed is there are registry entries for a bitdefender firewall NDIS driver, and i can't seem to find out how to remove it. I don't understand why bd wont simply overwrite other installations. i'm running windows vista home premium x64. thanks in advance for anything!
