This problem of missing serial ports has been a plague in the Arduino world for most of ten years. It is even worse if using Arduino IDE on a Mac. A google search finds MANY reports and multiple fixes, but none that are AHA! definitive.?
Very irritating.
Helmut - Windows is seeing the device and loading the correct driver and creating a serial comm port 5. All good.
Have you included the library for the Si5351? Nothing will work until you add the library for the controller. The Nano has a boot loader installed and should not need use of a programmer.

I have that same "no port showing up" problem every day. I've looked for a good reason for it, but can't figure it out. My fix: close down the IDE and then do a complete reboot of the system, from total power off to turning the computer back on. Then, the first thing I do is open the IDE and check the COM port. If none is selected, I select the COM port I have dedicated to the IDE. That usually solves the problem. Why? I don't have a clue. (If the COM port you select is in use with some other device, clearly that's not going to work. I had that kind of port conflict in the past, too.)
Let me know if it works for you.

Did you run the proper install program in the drivers subdirectory?
?Thanks Jack, I think there could be a possible cause for my problem. When I connect the Nano to an USB port, it shows up as COM5. So I just used COM5 in the Arduino ide. Is there anything else I have to do?
Got my old programer connected to the Nano, but get no Com port shown up. Have to use AVRDude, but hate to mess around with commandline paramaters. Have to look if I can find some GUI for it. Would prefere to just use the arduino ide though.
