I see "Bitdefender Virus Shield" as VSSERV service. Disable it or uninstall it and try again.
HTH
And that was it. I uninstalled Bitdefender (I had previously just stopped it) and it is now running. It believes it has 12 hours to go, so I can just let it run.
So, my question now... Apparently 6.2 doesnt support XP. Is there a version I can download that does? Do I just let this run? Or should I stop it and do it with something that is supported?
