(1.16.4 )Need to run minecraft manually at least once error

[Bruceplayz747]

Hi! So... I have this problem where whenever I try to install forge...An error would pop up saying I need to run minecraft 1.16.4 manually at least once...So I did, But when I tried installing it again it still has the same error...I did everything I can, I restarted my computer, I also searched for tutorials on youtube but I can't seem to find the fix for this. I don't know if this is just my pc or maybe something else... Please help me, I would really appreciate if someone would.

The error that popped up:

Just copy and paste it I guess..

You downloaded the wrong installer.

1.16.4 != 1.6.4
