Hello Marc,
Thank you for your response.
Yes, you may install an old driver on Windows 8.
You may refer this article and check if it helps.
Refer:
Make older programs compatible with this version of Windows

Note: Refer "Change compatibility settings manually" section in the above article.
I hope this information helps.
Thank you
It's actually not a 'program' that I'm installing. It's a Hardware Device, so the DRIVER needs to be changed. I have the USBAUDIO.SYS file from my Windows 7 computer, how do I use this instead of the updated Windows 8.1 version?
