AVG PC Tuneup will not start

I have been running AVG PC Tuneup on Windows 10 for over a year. After a recent windows update I tried to start the program but it will not start. I have used the AVG removal program to remove, restarted windows, and then reinstalled, but it still will not run. Any suggestions.
