Setup tested

This guide was tested using:

To install Base Client

  1. Download the Base Client. I downloaded the torrent file using Transmission. The default directory it downloads to is your Downloads folder.
  2. Open up Steam.
  3. Add a Game > Add a Non-Steam Game, Browse to your downloaded folder 3.3.5-enUS-minified and choose Wow.exe. Add Selected Program.
  4. Under Manage > Properties of Wow.exe > Compatibility, check the box Force the use of specific Steam Play compatibility tool
  5. Choose Proton Experimental
  6. Click Play, if it installs correctly you should get a Login screen. Quit out of this.

Installing the Epoch Updater

  1. Download the Epoch Updater client.
  2. Open up Steam.
  3. Add a Game > Add a Non-Steam Game, browse to epoch-installer.exe. Add Selected Program.
  4. Under Manage > Properties of Wow.exe > Compatibility, check the box Force the use of specific Steam Play compatibility tool
  5. Choose Proton Experimental
  6. When prompted, browse to your WoW installation, which you will find in / then home/your username/Downloads/3.3.5-enUS-minified, click Install.
  7. When completed, run the game from Steam by running the Epoch Updater (not the original Wow.exe)
