Thanks for the help. But I'm not sure I did this right. I double clicked the.exe file and ran the application from my downloads folder. I got a warning saying that the drivers I was about to install were older than the ones already had.

So I chose NOT to install them. Then, I went to the device manager, right clicked the PCI Serial Port, then chose update driver. I browsed to the new folder and and Windows 10 said that the device was properly installed. However, the device changed from PCI Serial Port to 'Intel(R) Active Management Technology -SOL (COM4)' Did I do this right?
