I'm trying to help out my son with an Alien vs. Pred mod. He has other mods for 1.7 and usually plays that all the time. This new mod he wants is only for 1.12 or 1.10, both of which I didn't have downloaded. So I download both forge 12 and 10, but I get an error saying "An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience".
Can someone please help me out with this?
I did have to install a new version of java to load the mod if that makes any difference.

You can only use mods for the Minecraft version they were designed for.

I see. I thought that may have been part of the problem. Is there a way to have mods for more than one version at the same time in the mods folder? Since most of the mods that my son uses are on 1.7.10, is there any way to make a separate mods folder that I can store 1.12.2 mods in?
Or is the only way to have Mods at all is to have them all for the same Minecraft version?

I made new folders for each forge version as you suggested and it seems to be working great. Basically I went into the application support folder and copied everything in the minecraft folder. I created a new folder named Minecraft 1.12.2 and pasted all into that new folder. Made the path to that for each forged version using the Launch options.
At the end of it all, it turns out that the Alien v Preditor mod isn't working. Something about it missing a mdxlib mod 1.12.2 file or something along those lines. Got any insight into that?

sorry about that. Here is the crash report. https://paste.ubuntu.com/p/96tS3NgG8F/
In your crash report: Time: 10/9/18 6:12 AM
It's not the right one.
sorry about that, I just grabbed the most recent file. Apparently there is no crash report, that file from 10/9 latest file in the crash folder.
the only file that was created today was in my log folder. Here is that report if it helps any. https://paste.ubuntu.com/p/PXr6vtkVZt/
I seems that you messed with 1.7.10 with 1.12.2.
You can only use mods for the Minecraft version they were designed for.

Make profiles for 1.7.10 and 1.12.2 with paths set to separate directories for 1.7.10 and 1.12.2.
To change directories, please read this guide: https://help.mojang.com/customer/portal/articles/1475923-changing-game-versions
Thanks ConorGarland.

Aliens vs. Predator requires MDXLib.

you are the man ConorGarland. Thanks
