Ah, there was an adf.ly prefix. removing it gave me an uncorrupted file.

Like I said, I already tried the .exe, it gave me the "can't run on this pc" error. I got the files from http://files.minecraftforge.net

Hey, It seems I'm havig the same problem as a hundred other people, yet I've found no solution in other threads. I downloaded the .jar, but double clicking it gives me the error "invalid or corrupt jarfile". I tried running it manually with command prompt, but it gives me the same error. I downloaded and run jarfix, but it didn't help. I tried the .exe installer, but that gave me the error "this app can't run on your PC" I'm running windows 8 (64 bit) I've copy-pasted all three errors to a jpeg, though it doesn't provide you with any new information, but screenshots were asked in other topics, so I'll provide it.
