I am installing PSM7 on a new Windows 10 machine and is says the dongle is not found. I installed the right driver for the parallel port (we have the old style of dongle). Any ideas? Thanks.

I'm not sure if that's supported.

This looks similar but it doesn't appear to have been resolved/answered:

Try opening a support ticket with Objectif Lune, you may be able to get that dongle swapped with a new USB style dongle (same license).

I'm using version 7.2.1 without OL support, that version isn't compatible with windows 10, I would have to pay $2400 for support and a version upgrade. I will just keep using 7.2.1 on my windows 7.
