Understanding licensing for older versions.

[RenoPowers]

I can't explain how clueless I am about this. And I'm sure it's all been discussed before, but after some internet searching, I haven't figured it out. I'm also crossing streams with Mac and Windows a little, so I'm sorry.
Feel free to point me at older threads or run me off if I'm too far out of bounds here.

My question... is there a version of PT that I can download for my windows 8 box, which would use the Digi 002 and/or 003 hardware device as the license?

Some back story... I have been given two older Mac G4s and a Digi 002, PT's 6.1 disks for Windows and Mac. I suspect the Digi 002 isn't working, so I've also borrowed a Digi 003 to confirm that. One of the Mac's may not be working either...so that's like a double negative in my testing.
There's a longer story about why I'm working on this older hardware, but it's not completely relevant. Suffice it to say, I'm trying to help a friend and learn some Mac and PTs stuff at the same time.

What I understand about PT 6.1 is the license for the software is the Digi 002 being attached. I'm assuming the Digi 003 would also work as the license/hardware dongle if I could get it to work. I'm assuming this is the same for Mac and Windows.

I'm struggling with troubleshooting on the Mac (for various reasons) so I'd like to move to my Windows platform to test.
The PT 6.1 disk for Windows won't install, says it requires XP and fails out. Makes sense ... 6.1 is much older software.

So I'm trying to determine if there is a version of PT that I can download for my windows 8 box, which would use the Digi 002 and/or 003 hardware device as the license?

Appreciate the help and I'm here for follow up questions or clarification if needed.
