I've followed the instructions on this site for downloading and installing minecraft forge version 1.7.9 but when Java tries to install the files I get an error that I "need to run version 1.7.2 manually at least once." What does this mean, I've opened and played the game several times.

  • Are you installing the mods to a separate profile? Forge needs a place to put the java files, so unless you're modding an existing profile (bad idea), that place doesn't exist yet.

    1. I have no idea what I'm doing and 2. I'm trying to install the Forge for version 1.7.2 and the game version I have is 1.7.9. it appears there is no Forge for 1.7.9 yet.

When installing forge you need to run the version that you are modding first and THEN install forge. So if I am going to mod 1.7.2 I would first run it normally and THEN install forge.


Run 1.7.2 at least once before you install it.
