Realized that I had installed both NWN and NWN2 to .wine which is 64bit. They run fine, but looking at GOG games that will probably need 32bit so:

create the prefix
WINEPREFIX=~/.wine32 WINEARCH=win32 wineboot
installed a game:
cd "NWN diamond"
WINEPREFIX=~/.wine32 wine setup_nwn_diamond_2.0.0.15.exe

Ran it and of course got the blank screen for menus so:

to winetricks it
WINEPREFIX=~/.wine32 winetricks

and added ddr=gdi

Looks like it's running fine, but how do I know it's 32bit? Should I have put WINEARCH=win32 on the install command line above.
It created a desktop icon (I renamed the 64bit one) and that's what I execute it from...

Thanks! I did both:

kris@kris-Z97X-UD3H:~$ winecfg
kris@kris-Z97X-UD3H:~$ WINEPREFIX=~/.wine32 winecfg


and both go back to windows 2, so that must mean that the first .wine it created was 32bit, which I guess makes perfect sense since I am using the wine installed by playonlinux. Duh! Thanks! Now how do I remove the new prefix I created? I'll google...

Thanks!

the WINEARCH can only be set the first time when you create the wineprefix. It can't be changed afterwards.
So you don't need to add WINEARCH=win32 to the install comand line.

Thanks!!!
