I'm unable to patch three programs on Windows 10 Pro (64 bit). I'm receiving this message: Alert. We are sorry, but there was an error. Message: Value cannot be null. (Parameter 'Path1'). The programs that cannot update are: DesktopOK (x64), Display Driver Uninstaller, and Tor Browser.
I reset all settings to default. I uninstalled Patch My PC Home Updater with Revo Uninstaller, rebooted, then installed Patch My PC Home Updater. This did not fix the problem.
