How to force Wine into acting like 32-bit Windows on 64-bit Ubuntu?

It turns out that to make Wine run in 32-bit-only mode, one needs to:

1. Remove ~/.wine if it was already created in the 64-bit mode. (WARNING: This removes all stuff you have installed under Wine. Move it aside instead if you want to avoid dataloss.)

2. Set the WINEARCH environment variable to win32 i.e. export WINEARCH=win32

3. Then run wine (or winetricks, etc.)

Install playonlinux there you will have this option. It is a frontend to wine, and makes it far better.

This picture was taken on a 12.04 - 64bit system.

You can in an easy way copy all win32 files into .wine to substitute the lesser need to change all run commands as well. By avoiding doing to much changes to the system in another hand. At first, run the command:

WINEPREFIX="$HOME/prefix32" WINEARCH=win32 wine wineboot

Assume you already made a run of making .wine with 64bit compatibility. If not you are still able to make a folder called .wine instead in your home directory.

Then copy all content of prefix32 found in your home directory to your .wine content area both files and directories, first either backup or just remove the content in the directory .wine if you already are planning running 32bit arch of wine, don't overwrite content! Rather delete if you already made a backup.

Remember that directory .wine might be hidden, any use of seeing hidden files will make you be able to see the folder in your home directory. You can as well use the Go in Thunar with Ubuntu to either just go straight into the folder called .wine in the home directory and make the process as told here before.

You can run 32-bit Windows programmes on a 64-bit Linux machine with wine by installing playonlinux.

1. If you haven't done so before, install playonlinux: sudo apt install playonlinux.
2. Start the playonlinux GUI: playonlinux &.
3. Click "Install a program" in the left sidebar.
4. Click "Install a non-listed program".
5. If this is the first time you started playonlinux, you might have to click through two notification windows.
6. Click "Next", then select "Install a program in a new virtual drive"
7. Choose a name for your new virtual drive, preferably the name of the Windows program you want to install.
8. Leave all checkboxes unchecked on the next screen and click "Next".
9. Select "32 bits windows installation" and click "Next".
10. Click "Browse" to select the installation file of the program you want to install and follow the instructions of the installer.

Install Play on linux as said before , i did it in like 1 minute , What you need to have:

1. Is have a 32 bit wine version , like said before.
2. Next you need to press install
3. Click the text at the bottom that says something like install a program that is not listed
4. Check change wine version
5. Select the 32 bit version you have installed
6. Create a new virtual disk
7. Name it
8. AND THE MOS IMPORTANT:Select 32 bit virtual disk
9. Select the installer and install

Try to remove .wine and export a wine prefix:

$rm -r .wine
$export WINEARCH=''win32''
$export WINEPREFIX=~/.wine

$wine config

While you can not run within the same containers you can actually still have both by setting up Biarch. Please see this Wine white paper on setup. While hsivonen gives you the easiest answer this would be the way to achieve your desired functionality.
