Dell Update Error installing

I own a 4 year old Dell Inspiron 3567 laptop which I recently had an issue with Dell Update not being able to load. When I try to start the program it says "DU.Classic Has Stopped Working. A problem caused the program to stop working correctly." So I uninstalled the application, which happened successfully, but now when I try to re-install using the download file I had to install it from before, the Installer runs, but gives me the error, " This application is installed on supported systems only. If you have received this message in error, please contact Technical Support." I thought "Ok, well Support Assist Application has updater built into that so I tried using that as well, by running "Tune Performance" in the Support Assist application. It too would also last a couple seconds and say it's done, but when I look under the "History", the "Tune Performance" that I started, the program said was Aborted, when I didn't even stop the scan. I find it strange that both of these applications now don't work, when they worked for me just last week without problems. Has anyone else run into this issue, or can think of what steps I could try to remedy this situation? I am running on the latest Windows 10 Version 21H2. Thanks in advance for your help!
