Office 2007 keeps reinstalling at each startup of program

[Tsibob]

Hi
I've installed office Pro + 2007 (FR) on a dell laptop with Vista Pro
installed.
Everytime I open Outlook or any other Office progr., the installation window
pops open and it does a reinstallation. I have reistalled the program twice
- to no avail !
I don't have any other version on the computer...
I can see many hve the same problem on differnet forums on the net, but
suprisingly, I see nothing on the Microsoft website - either support or
forums...

Has anybody encountered this problem and is there a fix for it ?

Thank in advance

Thanks, Peter, for the link. I've downloaded the cleanup utility, but found
nothing to remove (Office specifically) after uninstalling Version 2007 -
After reinstalling Office again, the same problem is still present.

I'm open to aother options...
