We have received many reports of players that couldn’t install the game in their own language.
We’re not sure what is causing this bug at the moment, but here’s a small guide to fix it yourself:
- 1. Download the correct language file from the zip file below
2. Unzip the contents in your AoE2 folder, no need to move files around, it should put them in place automatically (it will ask to overwrite 6 files, allow this)
3. Play the game!
Chinese Traditional
Chinese Simplified
Spanish
Italian
