Vista SP2 Update error 800F0A07

[Astor123]

The SP2 update fails and I get a message telling me that the newer version is already install. The error code is 800F0A07. This is what is shows in the registry under HLM > SOFTWARE > Microsoft > Windows NT > Current Version :

BuildLab............6001.vistasp1_gdr.090805-0102
BuildLabEx.........6001.18304.amd64fre.vistasp1_gdr.090805-0102
CSDVersion.......Service Pack 3

I can't go back far in Restore System dates to go back to SP1 so how do I fix this?
Any help would be greatly appreciated.

First restore CSDVersion to Service Pack 1 +restart.If don't help export HKLM\Software\Microsoft\Windows NT\CurrentVersion key

Start>>Search>>cmd.exe and type

REG EXPORT "HKLM\Software\Microsoft\Windows NT\CurrentVersion" %userprofile%\Desktop\log.txt

On your desktop appear log.txt ->attache this file to post

If I have to do the whole new repair/install might as well get rid of Vista and pop in Windows 7. And that is exactly what I'm doing right now.

Thanks for your help.

I suspect it return error during repair installation.
