That was covered early on in the thread.

My techstream kept crashing, so I’m trying to find a ver. 12 of it. Anyone know where I can find it?

Sorry to hear it's been so difficult for you. Ebay has version 14 and 15 for about $25. I didn't see any v12. I would think 14 or 15 would be even better. Please educate me if I'm wrong.

What version are you trying to use now? Did you install with virtualbox software?

I'm not sure if this link will work, but excellent instructions to getting techstream up and running on a newer windows 10 computer: https://www.facebook.com/groups/Lexu...56978741099901

Let me know if you have problems with the link and I'll have another look.

Did you fix or upgrade software? I can't imagine you're giving up after all the effort.
