Due to a recent update in Dota 2 in order for Overwolf apps to work correctly you will need to add an additional launch command line using the following instructions:
- Open the Steam client
- Click on Library, right click Dota 2 & select Properties:
- Go to General tab
- Under Launch Options add the following command line: -gamestateintegration
Then relaunch Steam and Overwolf to save these settings.
