My 2 PCs run Windows 10. Chessmaster 10th Edition min config is Windows XP. Hours of problems trying to install it. Checked forums and Ubisoft. Found 3 patches. I can only run it on 1 of my PCs after great trouble and effort. Solution for 1 PC doesn’t work on other. Pgm is a little visually disappointing. Still etter than dealing with ads.
