I just purchased the Blizzard Arcade Collection and noticed an icon did not show up in Battle.net for the game. I downloaded the stand-alone installer and the following happens:
I get a popup with the following messages:
Downloading new files
Updating Battle.net agent
Battle.net then starts up and a popup with the following error shows up
We couldn’t find RTRO. Please reinstall it, or point us to its installation folder in the Settings menu.
More help: BLZBNTAGT00000975
There is nothing in the settings menu referencing the Blizzard Arcade Collection or anything called RTRO.
I tried completely uninstalling and reinstalling Battle.net without success.
