Program will exit.' i cant install mods cause of this. someone please tell me what the problem is and how to fix it. --Halo2554"

Hello! This is not a bug. If you try to simply 'open' a .jar file, your system will attempt to run it as a java program. If you want to modify the contents of the .jar archive, you need to open the file with a program designed for handling archives. WinRAR would probably work if you have it; personally, I prefer the free program 7-Zip. Opening the .jar file with 7-Zip shows you the contents and allows you to modify them, as you're looking to do. If you have any questions, feel free to reply right here. Good Luck! --timrem 18:53, 7 August 2012 (UTC)
