Forge 1.12.2 Won't Install

[SteveHoovey]

There is a problem when it comes installing forge. I have 2 existing forge versions in the installer but when I try to install 1.12.2 it won't appear on the installations. To be more clear after I had initially downloaded the file I then opened the folder set it to client and it proceeded to install. After that when I go onto the launcher it just isn't there

1.12 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.
