Could not find game installation directory​

You are getting the error message "Could not find game installation directory -- please join a lobby and run game diagnostics" when entering a game lobby or when attempting to install a mod from the Voobly Mod Center, even though the game is already installed on your computer. The Game Diagnostics (Menu Options > Game Diagnostics) also says, that everything looks fine.


Open Windows Explorer and navigate to the your game installation directory as shown in the game diagnostics results. Depending on, whether you have Age of Empires II (2013) or Age of Empires II (1999) installed on your computer, the path will be different.
  • C:\Program Files (x86)\Microsoft Games\Age of Empires II\ (1999)
  • C:\Program Files (x86)\Steam\steamapps\common\Age2HD (2013)
Create the following folder in your game directory: Voobly Mods


Enter the created Voobly Mods folder and create the required sub-folder, e. g. AOC for Age of Empires II.


Enter the created folder AOC and create the following three folders: Data Mods, Local Mods, Patches


Restart Voobly and check, whether the problem still persists. If you are still having the issue, please make sure, that the User Account Control (UAC) is turned on. Turning off UAC is not recommended by Microsoft, as it is a major security risk. Turning off UAC also breaks Voobly. When changing the UAC settings, your computer must be rebooted after.


Your problem should now be solved.

Voobly has confirmed that this is a problem in the Voobly client software listed in the Applies to section.
