Hi,
Using 4.20 wine-staging (Windows 7, 64 bit) and the now freely available original StarCraft (with 1.18 patches) from here:
https://www.battle.net/download/getInst ... =STARCRAFT
Battlenet is getting installed fine when running:
wine StarCraft-Setup.exe
Battlenet login also works, but after that, at the StarCraft installation screen, the Install button does nothing.
