Got a beta invite for ESO and of course I wanted to get it running in Linux. Little about my setup: I use PlayOnLinux on ArchLinux to manage my wine versions and to contain the bottles. I do not use it to do anything else honestly. Here is how I got it running on my install... I installed the game on a Windows machine at first, as wine has some bugs with the installer. There is a patch available to your wine version if you want to install it directly. This site might help you with that patch http://blog.internetz.me/2014/02/28/eso-install-linux-kali-also-works-ubuntudebian/ I then copied over the entire folder structure to my system to my revodrive I have mounted in /revodrive. (You can skip this. It is for me specifically.) I told PlayOnLinux to download 1.7.11 x86 version of wine. I then create the prefix to hold this bottle.

$ WINEARCH=win32 WINEPREFIX=~/.PlayOnLinux/wineprefix/ESO /home/username/.PlayOnLinux/wine/linux-x86/1.7.11/bin/wine winecfg
I then create a link from that bottle to my revodrive. (You can skip this. It is for me specifically.)

$ cd ~/home//.PlayOnLinux/wineprefix/ESO/drive_c/Program\ Files
$ ln -s /revodrive/Zenimax\ Online Zenimax\ Online
You can copy your entire "Zenimax Online" folder to the bottles Program Files directory. I needed to install a few things.

$ sudo pacman -S lib32-libxml2
We need to install VC Runtimes 2010 into the bottle, you can have PlayOnLinux do this. We need to install DirectX into the bottle, you can have the Installer do this. I used PlayOnLinux to install the vcruntime2010 in the bottle. We should now re-run the ESO installer to set some stuff up.

$ cd ~/Downloads
$ wget https://elderscrolls-a.akamaihd.net/products/BNA_Launcher/Install_ESO_Beta.exe
$ WINEARCH=win32 WINEPREFIX=~/.PlayOnLinux/wineprefix/ESO /home/username/.PlayOnLinux/wine/linux-x86/1.7.11/bin/wine ~/Downloads/Install_ESO_Beta.exe
Tell it to install in the default path, and it will complain that it already exists. This is fine, just continue. Once it's done installing uncheck the VS2010 runtimes box, uncheck the Play Game box and keep the DirectX box checked. Click finish and let it install DirectX into the bottle for you. Now we need to create a script file to run the game correctly, just like we did with Skyrim on Linux.

$ nano ~/.PlayOnLinux/wineprefix/ESO/drive_c/eso.cmd
Place this in the eso.cmd file

C:
CD \Program Files\Zenimax Online\The Elder Scrolls Online\game\client
eso.exe
Then we can run the game with (I put this in a shell script to make it easy.)

$ WINEARCH=win32 WINEPREFIX=~/.PlayOnLinux/wineprefix/ESO /home/username/.PlayOnLinux/wine/linux-x86/1.7.11/bin/wine cmd.exe /c C://eso.cmd
Run the command or script, you should get some errors and the game might run. Once you can close the game, do so. It should create a folder in the My Documents called "Elder Scrolls Online" under here we have two folders now "ESO_BUILD_BRANCH" and "live" go into the "live" folder and edit or create a file named "UserSettings.txt". If it does not exist create it and add one line

SET GraphicsDriver.7 "OPENGL"
If the file does exist open it and find a similar line, change it to the above. Load up the game and check your resolution settings. I set mine but it did not take effect. Exit the game, edit the "UserSettings.txt" file again and find the resolution lines, change to your preference. You should be able to run the game now. I had some trouble after logging in joining the game world, it seems like other games it does not like running through my VPN. I bypassed my VPN and used my direct WAN by allowing 198.20.200.0/24 to bypass the VPN. If you get an error similar to the following you need to change to OPENGL mode as it's trying DirectX mode. Also, the last error is resolved by running with the script above, or another way that changes to the working directory and running the eso.exe
