>Maybe try VFPClean.app it will see if the reg keys are broken...

I run it and everything was ok. So, the problem is not there.

When trying to rerun the instmsi.exe, it says that the service is already installed. So, all is ok with that part. When trying to click on vfp70sp1.msp, it prompts right away for the CD. The CD is already in the drive. I do however enter e:\ but that doesn't do anything. After a while, I have this message:

"The installation source for this product is now available."

I did however succeed to install it on my laptop. After several retries, the last one did work. Don't ask me why. After several retries, it finally worked on the laptop.

But, on my main PC, I can't do anything.
