Hi all, Every single Google hit on this subject under Vista mentions McAffee. I have never installed an anti-virus, firewall, security helper, etc. product on this box. I'm trying to start the Windows 7 backup application, and as soon as I hit "Set up backup", I get the error: The backup application could not start due to an internal error: Server execution failed (0x80080005). It turns out I cannot invoke Block Level Backup Engine Service. The error I get when manually starting that service is: -------------- Windows could not start the Block Level Backup Engine Service service on Local Computer. Error 0x800700b7: Cannot create a file when that file already exists. --------------- I traced using Process Monitor and it doesn't appear as though anything bizarre is occurring in sdclt.exe. I could be wrong, of course. Perhaps there's a permissions issue somewhere? Some help would be awesome! Update: This is a pristine image running Win 7 Ultimate RTM
