Vista - MS Office 2007 "Not configured for current user"

I have MS Office 2007 (Student edition installed) on a 6 month old HP Pavilion dv 3510nr. Twice now when opening any of the MS Office applications I get a pop up advising that "MS Office is not configured for current user" . I can proceed no further using the application. There is only one user account set up on my laptop. To get things back to normal I have to use a previous system restore point or else an Acronis disk image.

The installation of MS Office 2007 was a download trial that was activated with a key purchased from MS.

Any ideas what might be causing this, or more importantly can I back up a particular Office 2007 setting that will enable me to get things back to normal without using a SRP or disk image?

Thanks

Kanangus,
Try turning off UAC & see if the problem stops.

You could try Office Diagnostics to see if that helps.
