I’m getting an “exec format error” when trying to run 32 bit programs under wine-staging. I installed wine-staging with:

sudo pacman -S wine-staging wine-mono wine_gecko winetricks q4wine

Then I created a 32 bit WINE prefix:

WINEPREFIX=~/.wine32 WINEARCH=win32 wineboot

Afterwards I tried to run my 32 bit exe (Fallout New Vegas from GOG.com):

WINEPREFIX=~/.wine32 WINEARCH=win32 /path/to/your/32bit_executable.exe

It is then that I get the exec format error. Does wine-staging install any 32 bit components? It seem that wine and wine-staging cant coexist in Arch because they have conflicting dependencies. And I want to use wine-staging rather than wine because it has additional patches like CSMT. Is there an easy way around this?
