Sometimes Windows has a hard time finding the drivers or getting them installed correctly. Please download the drivers to a known location. The open the device manager and look for "USB COM Port" (or something similar). Click through and then click "Update Drivers" Choose the manual option and point windows at your drivers folder.

You should see a new COM port in Windows when you get the drivers installed correctly.

That's the best I can do for Windows troubleshooting without seeing the specific machine.
