Just downloaded the PCR-M50 drivers, the .inf file is "RDIF1027.INF" inside the "pcr_w764d_v100/Files/" folder.
Open RDIF1027.INF with notepad and search for below:

Looks like the driver is older and was made for Windows 7, not even 8 or 8.1.
You could perhaps try using the same string for Windows 7 and duplicate this for 8, and add an additional clause for 10.
Such as something similar to this:-

(Red shows what I've added).
I cannot guarantee this will work as I'm unfamiliar with the intricacies of Microsoft code, and furthermore don't have a PCR-M50, I cannot test it, it's merely a hunch.
