The Blizzard launch app has been flashing an error message. It happens every 10-15 minutes that the app is running, regardless of what I am doing, . It simply says “Something went wrong while trying to launch a program. Please try restarting Battle net and/or your computer.” I did what it suggested and also uninstalled the app and downloaded a new version from the Blizzard website. Nothing so far has fixed it.
I am still able to launch games, so I don’t know why the error is popping up. Occasionally WoW will freeze on launching, but that is it.
