Sorry for what I say but WeMod suck very much... I can't install it at home & at work too, many friends in France can't too... Why? IDK... Country France banned?
Anyway for who want to cheat & except if you play on server, you don't nead a trainer with this game!
Just go learn how to mod yourself with .xml files here:
...\Steam\steamapps\common\7 Days To Die\Data\Config\
It's very easy & no need to be a pro dev... Example with entityclasses.xml at the line 69, replace this line by this:
<passive_effect name="HealthMax" operation="base_set" value="9999"/>
In game, you will have 9 999 HP !
