Hi. Thanks. I tried this, but it actually didn't help. However, after doing a bit of searching on GoogleGroups, I found a fix by doing the following:
1. Restart WinXP in Safe Mode
2. Double-click on the installer to start the install process
3. Cancel the install process after it starts up
4. Restart windows in normal mode
Now all my setup.exe's and MSI applications work fine! Pretty strange. Just for the record: this problem was not due to a Virus-Protection program (as many people would first guess) and it prevented me from running ANY installer (MSI?) applications from a CD.
