I'm not so sure that PT 11 won't run on Win 10, but to be fair, I didn't try it. I do have a PT 10/12 co-install working just fine on Win 10 Pro, though, and it seems to me that if 10 will run on it, 11 should too. (From what I found on Google, a 9178 error = running out of processor power. Good time to post some system specs.
