Just as ggunner has pointed out, it is necessary to create a virtual serial port. I found and used this great little program:
Once installed, and you runt it to create the virtual port, you may see in the log/progress update a message that says "Winsock error 10061" - I ignored this error and double clicked FMS.exe, and it ran without any problems!
Hope this helps, and thanks ggunner for the tip!
