Hi I'm trying to play the Halo Craft mod for Windows and I downloaded the proper Minecraft Forge for the mod which is 9.11.1.965 and it runs on Minecraft 1.6.4. I have the mod and I know where to place it, but the game just won't launch the Forge version of the game. I click play and the window closes. The latest version of the game works but not the Forge version. I have Java 7 because I'm running Windows 8 and I have NOT edited the .jar file. Somebody please help I would greatly appreciate it.

Hi,

1.6.4 is no longer supported, please update to 1.7.10

If you really want use an old release, you are in your own.

 

I suggest you anyway to install this mod : http://files.minecraftforge.net/LegacyJavaFixer/legacyjavafixer-1.0.jar

It is very likely that your game runs with Java 8 if you have Java 7 and Java 8 installed, install this mod should fix your problem in this case.

 

For the next time, don't forget to give us your log.
