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

This product is not supported on a 64-bit OS.

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

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

winearch=win32 WINEPREFIX="/path/to/new/wine/bottle" winecfg

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 Jul 10, 2017 at 20:33
