Troubleshooting

Nothing happens when I launch VU

If nothing happens when you launch VU, try validating your game files via Origin and launching the vanilla game via Battlelog at least once (you can launch either singleplayer or multiplayer). You can also try downloading the latest version of VU and re-installing it.

I get an EA activation prompt when launching VU

This prompt may appear after major Windows Updates or hardware changes on your computer, and is part of Battlefield 3's DRM system. Simply fill out your Origin account credentials and follow the prompts to activate your game. Alternatively, you can launch the vanilla game via Battlelog or run the VU executable with the following launch arguments (where <email> is your Origin account e-mail and <password> is your password):

vu.exe -activate -o_mail <email> -o_pass <password>
I get a black screen / loading screen when launching VU

If you're on Windows 7 and you're getting a black screen or a black screen with a loading indicator, you need to install the KB2670838 update package. After installing this update VU should work as intended.

I get returned to the main menu after joining a server

If you get returned to the main menu after joining a server it could mean that there's a discrepency between your local files and the server files, so the first thing you should try is validating your game files. If that doesn't help, it probably means that the server is running a mod that causes this issue, so the only thing you can do is contacting the server admin for support.

I get an "Could not locate your Battlefield 3 installation directory" error when launching VU

This means that VU cannot find where Battlefield 3 is installed on your system. To fix this, simply validate your game files via Origin and launch the vanilla game via Battlelog at least once. If you have transferred your game files over another computer or you're running this on a machine that can't run Origin, you can manually specify the game's installation directory by using the -gamepath launch argument, as seen below, where <path> is the path to the BF3 directory:

vu.exe -gamepath <path>
