Thank you for replying, but it didn't work. I got the same error. "Failed to run processor: java.io.EOFException:Unexpected end of ZLIB input stream. See log for more detail."
I've been trying to install Forge for a few days but when it's almost done it fails and says "Failed to run processor: java.io.EOFException:Unexpected end of ZLIB input stream" I've been trying to find help online but i don't know.
