PS Elements v 18 and WIn 11

My Photoshop Elements 18, recently re-installed to run on PC with WIN11 update,  has given great trouble with the "update" offered. the update hung and uninstall would not run either. A cold boot, uninstall of application, fresh installation. It took me most of the day to get these steps in the right order. I have now decided to use the application without running the update. Any suggestions graefully received
