I bought autocad in the beginning, 2.9 I think. Upgraded through the years to version 2000. Spent a lot of money on it. The computers that run it have all finally failed. New machines running windows 11 won't run it. Not going to spend any more money with Autodesk, well over $10,000 dollars. Looking for options to make my version 2000 run on W 11. Tried knock offs and thought about buying used computer with earlier version of windows. I have no speed with knock offs and don't want to fly around with multiple computers. Open to suggestions?
