i've worked around this by using winecreateprefix to create a new prefix called .wine2 which is 32 bit as it was created by wine.i586. I've copied my wow files across from .wine, verified they run using Code: env WINEPREFIX=~/.wine2 wine ~/.wine2/path_to_wow.exe then renamed .wine to .wine_old, and renamed .wine2 back to .wine all works properly now, but I can't help but think there must be some easier way to move the 64 bit prefix to 32 bit.[/code]
