If you're having trouble installing Support Assist

Support Assist wouldn't install after I reset my computer. This finally worked: https://support.microsoft.com/en-us/topic/fix-problems-that-block-programs-from-being-installed-or-removed-cca7d1b6-65a9-3d98-426b-e9f927e1eb4d

After downloading and opening the troubleshooter, it asks if you're having trouble installing or uninstalling a program. Choose "uninstalling" and if you see Support Assist in the list it brings up, choose that. It fixes some files. Then I restarted and reinstalled Support Assist and it worked.
