Rakious, your issue is simple and is not the same reason the OPs is failing. So jarganaut this fix will not work for you.
Your Minion.xml has two games with the same unique-game-id. The easy fix is to delete minion.xml and restart Minion. The better fix would be to remove the following from the minion.xml and save then restart Minion.
Code:
<game addon-path="C:\Program Files (x86)\Zenimax Online\The Elder Scrolls Online EU" auto-update="false" game-id="ESO" ignore="true" unique-game-id="ESO-2">
<addons>
<addon md5="6c0a1ae86861be9ed217c2cff7e2826d" ui-version="1.7" uid="18"/>
<addon md5="54d2816f18414314229c7a50032f2e9f" ui-version="0.3" uid="29"/>
</addons>
</game>
This is the result of removing a game from the game list and then adding another one. There is currently a bug where it will assign the new game you added the old gameid. We are working to fix this.
