How to run WineTricks in 32 bit mode on a 64 bit system

Question

I am using WineTricks to install some DLLs, but I'm encountering this problem when installing .NET framework:

So, how do I run WineTricks in 32-bit mode?

Solution

Set up a 32 bit Wine Bottle Prefix on a 64-bit System by using Wine Bottles, like so:

32-bit:
winearch=win32 WINEPREFIX="/path/to/new/wine/bottle" winecfg

64-bit:
winearch=win64 WINEPREFIX="/path/to/new/wine/bottle" winecfg

---

Never use the default WINE bottle. Use winetricks to select the bottle.

just to add a tip, when running a 32bit application on a 64bit prefix, while calling wine64, we need to unset WINEARCH b4 calling it, or it will also give "bad exe format" error
