Thanks guys. I can run a computer but I need instructions like “press this”, “do that” otherwise I’m stuck and do not know what to do. When I got that incompatibility message from W7, I was lost. I checked some websites but they all wanted me to down load something which I won’t do. I could really use a long list of instructions. I tried Autodesk but got tired of running around in circles. There was nothing definitive there. I’ll keep trying. Dan.
