Solved!
When trying to install the faf update the client told me that I was not logged in. I never got a login screen. After a few tries I was getting a error. So I tried to uninstall. But I keep getting the same error.
I uninstalled Java and reinstalled it. Restarted computer a few times and did part 2 of the fallowing website. https://appuals.com/jvm-could-not-be-found/
It still doesn't work. Does any one know how to solve?
