--- Comment #2 from Josh winehq@iooioio.orion.uberspace.de --- Thanks for pointing that out. I can confirm that switching to a 32bit executable (nothing to do with color) from the battle.net client got me all the way to the main menu. I can't do any further testing right now though so not sure how useful this workaround actually is.
