FSX registry cleaning

I ran the mskb928080 program eactly in accordance with the instructions in the ReadMe file, the command prompt returned:

c:\MicrosoftKB928080>resetsldl /a
Cleaning up Token Store at: C:\ProgramData\Microsoft\SLDL\\SoftwareLicensing
Failed to delete the token store.
Error -- HRESULT 80004005

Would be grateful for guidance on what to do next.
Thanks
Robert

Thanks RadarMan, I have already followed the advice given in the link you quote - which is why the outcome is so disappointing and frustrating.

What exactly is the error message that you are trying to clear up.
