Fixing Installation Errors

Vanilla EU4 Loads Instead of ESU
This is an issue with either Steam Workshop or the Paradox Launcher. To fix it, you should follow the steps for Reinstalling ESU.

ESU Crashes While Loading
Ensure that you are not using any other mods while running ESU. Due to the sheer scope of the changes that ESU makes, it is unfeasible to maintain compatibility with other mods. If ESU still crashes despite being the only mod enabled, then there is likely an issue with the installation. In that case, follow the steps for Reinstalling ESU.

Country and Province Names Appear Incorrectly
ESU only supports playing EU4 in English. Changing your game language to English in the launcher will display the proper names for countries and provinces.
