Patching up your PC won't run

Scanning finds only 4 trackers, 5.28MB of junk Custom cleaner runs, but after scan "Patching up your PC" will not start or run. What other than delete and reinstall will correct? Cleaned registry, backed up first, Rebooted PC does not fix. Running Windows 10 with updates.
