Couldn't start Wakfu, now can't even install it

Good evening, i'm a new player to your game, despite playing it in the past for about half an hour (And i enjoyed it!).

However, now that i bought a new and properly updated PC, i can't get the game to start through the launcher. I tried repairing it, and then it kept asking me to repair.. i tried reinstalling the game, and now it keeps asking me to install, no matter how many times i do it.
I went through some old topics about Java versions and iGPUs (which i do have an installed integrated graphics card at the moment.) however, those did not work.

So, i ran out of options, what do i do?
