I'm stumped at the moment. The company I work for produces it's own in-house software that is sent out to clients. A few weeks ago, an employee called reporting that he had tried to reinstall his software after screwing up his previous software configuration, and it wouldn't work. While walking him through it on the phone, I couldn't get anywhere.

Then, while trying to do the same thing on my computer (reinstall the software), I had the same problem! This is an coincidence because on the vast, vast majority of machines we use this software on, this problem never arises. In fact, this is the first time it's ever happened. It just so happens his and mine machines are the two trouble-makers by chance. Here's the details on the problems:

1) Try to install the software over the previous installation. Installation fails.
2) Removed previous software. Reinstallation fails.
3) Further removed all folders for previous installation. Fresh installation still fails.

In fact, the computer won't even try to install it. Autorun of the installation CD fails. When I go in to the CD drive folder and double-click setup, the green light on the drive lights up (it's at least reading), but nothing ever happens. Tried it from the command line, same thing.

Of the countless machines this software is installed on, only these machines are exhibiting the problem. But I can click on setup.exe all day and nothing ever happens on these two.

Any suggestions guys? OS is W2k.
