Has anyone used ADT on a Windows Vista Business or Ultimate OS? We’re getting ready to upgrade our systems and currently we are using ADT on Windows XP Pro (32bit). Would it be worth upgrading the OS to Vista Business or Ultimate? I know ADT v8 does not work on a 64 bit system. Actually there is a fix for it but I won’t go that route. I would prefer to stay with a 32bit system in XP or Vista.
