QSettings windows registry reading fails on certain keys

[Kwakkie]

Thanks for the idea. I've tried this with SerialPortInfo::availablePorts(), but the port I need doesn't really "exist" as a serial port (it is some kind of virtual comm device). So unfortunately this won't work for me.

Your virtual device is present into Device Manager?

[Kwakkie]

No it isn't listed there.

Edit: to be fair, I'm not sure why that would be relevant. What if I wanted to read a completely different key starting with a "/"?

No it isn't listed there.

Then yes, you need to read the registry. Instead QSettings, try WinAPI I think it will be easier.
