Installation went smoothly.
After installing it offers to upgrade to a 10 day trial of version 26 Pro, the latest version. This can be extended to a 20 day trial. Prior to it downloading and installing version 26 Pro it has to uninstall version 25 Pro. I don’t know if it reinstalls 25 Pro after the trial of 26 Pro, but I doubt it. I chose the trial anyway. After it installed without issues, and announced it could be 26 Pro could be bought for $20 instead of for about $66. As I have yet to test the program I’m not prepared to make the decision.
