I have an Inspiron 15 7000 now running on Windows 11. The latest version of Support Assist will not install simply saying "Installation failed please restart your computer and try again". I have tried uninstalling the old version of Support Assist (3.10.4) and then reinstalling but without success. Any suggestions would be most welcome.
