How to put my forge mods on aether 2 (they're all v1.6.4)?

This keeps popping up, forge mod loader has found a problem with your minecraft installation. The mods and versions listed below could not be found.

Forge: minimum version required 8.9

the file 'ForgeModLoader-client-0.log contains more information

and when i install forge again it says the directory is missing a launcher profile.

your answer is appreciated, thanks

Go to skydaz.com they rock and have mod installers. Not a scam. But it only works for Pc.

If you want to know how to install a mod that is like 1.6.4 first go it your minecraft launcher and make a new profile and set it to release 1.6.4 in its settings. Then hit play, once it's at the menu close minecraft. Go to the forge website and download 1.6.4 INSTALLER it may bring you to adf.ly just hit skip ad in the top right. Once downloaded hit install client or something alike. Close that. Go to mod website WHICH HAS TO BE THE SAME VERSION AS THE FORGE YOU DOWNLOADED. Download it, drag it into the mods folder and boom.
Tips: Make sure when installing forge that the version you install to is the one you want example 1.6.4 in a drop down arrow.
Start with clean minecraft! No mods installed!
