The data.vdf file (which contains the text entries for the language.dll file) was in English. I'll release a Spanish language version of Age of Middle Earth! Age of Empires II: HD Edition. Why doesn't Aoe II HD have a language.dll file? Pretty important file, I thought, and everyone mentions it, but I can't find it anywhere. With the correct folder path. I also have a modded language file and it works ingame without problems.
You have to place the modded file with the correct ids included that you want to replace into your mod folder, with the correct folder path. I also have a modded language file and it works ingame without problems. ( i renamed the crocodile -> Alligator) take a look here: and thats my folder path, where i included the key-value-modded-strings-utf8 C: Program Files (x86) Steam steamapps common Age2HD mods TEXT + ICON resources en* strings key-value *depend on your language in the modded text file i included: 5060 'Alligator' in the original file its: 5060 'Crocodile' so it will just replace the ID 5060. Welp, I didn't wanna respond until I tried absolutely everything, and I'm growing very frustrated here. So I tried exactly what worked for you, and it still didn't function. Mod-status set to enabled=yes and local=yes (seeing as I'm creating it.) 2.
Path used is C: Program Files (x86) Steam steamapps common Age2HD mods jpgamerebalance resources en strings key-value key-value-modded-strings-utf8.txt 3. 
Changed 5060 'Crocodile' to 5060 'Alligator' I triple checked to make sure my path wasn't messed up, and I, an aspiring modder, am getting pretty disheartened. Have any idea what I may have missed here? Also tried renaming it to regular key-value-strings-utf8, and nothing changed. Muljtivarka leran instrukciya po primeneniyu.
