Error: You need to run the version 1.16.4 manually at least once

I am trying to install forge so i can use Litematica, but every time i try to do so, i get the Error: You need to run the version 1.16.4 manually at least once. I have run version 1.16.4 multiple times but it still isn't working. I have tried deleting the game(going into appdata and COMPLETELY deleting the .minecraft folder), restarting my computer, reinstalling forge installer, and getting an older version, but NOTHING works. The only problems i can think of is i have a minecraft 1.16.4 server running on this computer, but i can't stop that or the players would get upset, or i have an old version of java( but i'm not getting any notifications about it, so i assume that isn't a problem) If anyone has a solution to this, please let me know.

1.6.4 != 1.16.4

You're running the wrong installer if you're getting this error.
