ok, so im not really sure how to explain this, so i'll just post a screenshot. i followed a tutorial on how to start a server from forge, and everything went smoothly until suddenly, the below screenshot pops up. it says that it's not installed, but it's literally right there.
i'm dumbfounded. i've tried everything i can and nothing seems to be working, it just shows the same error over and over again, without fail. i've reinstalled forge more times i can count, and tried every tutorial i saw on the matter, and still, nothing. so im coming here for help. if anyone can help me fix this problem, i would be very grateful. screenshot below.
