Hi All
I seem to be having a problem on one of my PCs [XP Pro] with windows installer when installing any setup executables I get the following error message:



Tried MS installer reapir here which basically renames files and reinstalles the latest version still no joy

Starting the service manually gives me this error message:



Event log gives me this:

Event ID 7000

The Windows Installer service failed to start due to the following error:
Access is denied.

Anybody seen this before ?
TIA 10

PS cant run Windows Installer CleanUp Utility as this gives the same error message.
