Don't make duplicate threads, especially when someone is already trying yo help you. Do you not know what a file is? Do you not know what a folder is?

You select Forge from the version dropdown

Threads Merged, stop asking about 1.8.9

I mean you are running vanilla, not Forge

Please provide your debug.log for the actual issue

Then you probably aren't starting Forge
