Jan, I can try to help - but first can we be clear about which problem it is that we're trying to track down?
If you're worried about correct installation, then I've had no problem with that on Windows 10 - i.e. I get the four ports installed and correctly named "RRC1258 COM0", etc. From that point of view, everything looks normal.
The problem I have is that the ports only work correctly with a few programs, and not with others. For example a port used for CAT, in my case, only works in N1MM+ and OmniRig, but not in DxLog, WinTest, DxCommander and others - all using the same settings. I guess there must be something different in the way those programs open/use the com port, but I can't figure out what it is. It certainly seems to be something specific to Windows 10, so it could well be out of our control...
Regards, Mark
