I've been wanting to get the pixelmon mod up and running ever since I heard about it, so I'd really appreciate any help. Thanks!

Doesn't look like it's installing correctly. What archiver are you using, and what methods are you using to install it? I recommend 7-Zip (Free) or WinRAR (Free trial) if you insist on adding the mods manually. If you'd rather not do it manually, I'd suggest MultiMC or Magic Launcher. MultiMC is more user-friendly, and Direwolf20 has doing an

for the latest version.

 

(You can find a link to each of those things in a previous post I made here)

Thanks for the quick reply Zero. To be honest I have absolutely no idea how to install it manually (my brother and I were just trying to follow the tutorial from the wiki), so that MultiMc thing sounds great! I'll post back after trying it to let you know how it goes.

 

Thanks a bunch!

Just wanted to let you know that it worked! Thanks again zero
