Bitdefender Free: Can't uninstall or reinstall


Hi, Using Win 10 x64 and I needed to do a system restore but it failed and blamed the antivirus so I uninstalled Bitdefender Free and the restore completed OK. However when I try to reinstall Bitdefender Free it downloads OK but then the setup bombs out with 'Install Error. Cannot copy installer.' When I checked under Apps it still lists Bitdefender and all the Bitdefender directory is still on the drive full of Bitdefender files so I tried uninstalling to get a clean run at reinstalling but the uninstaller just bombs out and does nothing. I found an uninstaller tool on the Bitdefender website but it can't remove the old installation. I read this thread and am hoping somebody might have a URL for the tools mentioned
