Not updating to 5.8

I'm having a problem trying to update CCleaner Pro to version 5.80. I click on check for updates, update now, the progress bar goes to 100% then nothing happens. The update program closes but the program does not restart. When I open the program again, it's still at 5.79.

Suggestions?

Downloaded program from scratch, which asked for license key and name. All went well and now it's at 5.8
