Hey there friends,
Hate to see people having trouble like this. If Beta is installed, it should be a drop down above the play button. If you uninstall it, you should not have the option to reinstall the beta.
As for the fix of making sure your keys are added. These can be added on the main page of your battle.net account.
If still having problems locating or claiming your keys, please reach out to support with the CD keys you have added to the contact.
Last, I would want to fully delete/uninstall the game and the Blizzard app.
Perform Steps 1-5 here after that do not reinstall yet but follow these additional steps:
- Open file explorer/file manager
- Type the following into the address bar (not the search bar): %APPDATA%
- Delete the Bnet and blizzard folders inside the appdata folder if they exist.
- Repeat steps 2 and 3 with %LOCALAPPDATA% and %TEMP%
- Empty the recycle bin.
I hope this helps.
