Windows Installer Problems!



Well I'v tried posting this problem a number of ways on different forums and not got any where near a solution. So here goes with a fresh approach.

I keep getting the following message whenever I try to alter, remove or update a software installation:-

"The installation source for this product is not available. Verify that the source exists and that you can access it."

The problem at first seemed to be just MS Office 2003. This message occurred in the above situations and whenever I attempt a "Detect and Repair". BUT the problem cannot be with Office as such because I have the same problem with various Serif and Corel products. The problem must lie with the Windows Installer sub-system. Even when I try uninstalling and re-installing the problem remains. Note: the only way I can uninstall is by using the Windows Install cleanup utility first because of the above error message. I have updated the installer software form Microsoft and this has made no difference. I suspect that the registry may be suspect but where do I start?

Can someone please help as this has gone on for months now with no solution.

Many Thanks
.
