Lambert, i am also getting the same error when running the restore tool. I have tried a complete removal and the cleaning out the registry and files left on the disk and then reinstall...same error. The thing is I had 4.2 installed and it was working. it was the upgrade to 4.3 where it went all wrong...and this versions is meant to support vista. I have it working on my tablet which is running vista. This I upgraded from 4.2 with no issues, which is why I done the PC straight after, but the outcome is not the same. I get the impression that the installation of SS software is never consistant
