--- Comment #27 from simon skosecki@gmail.com --- No. What I mean that the game can be re-installed via Battle.net client. I deleted Program Data/Battle.net folder and removed old Starcraft II and Diablo III folders under Program Files (x86) within the prefix. Then under Wine Staging 5.9 it allowed me to reinstall those two games from within the battle.net client.
On Staging 5.10 and 5.11 games won't update and even when folders are deleted and re-installation is attempted they fail to download/update. Starcraft II starts the download then fails, Diablo III doesn't even start the download.
Also looks like after reinstallation under 5.9 both games run. But after upgrading to 5.11. Diablo won't start anymore.
Both games work on 5.9 ok
