I just tried launching forge on 1.6.4 and i used the installer named "forge-1.6.4-9.11.1.965-installer.jar" and it installed. I open the minecraft launcher and i click play and then it closes the launcher but it reappears because of a crash. The console says this: Feb 16, 2015 10:33:22 PM net.minecraft.launchwrapper.LogWrapper log INFO: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker Feb 16, 2015 10:33:22 PM net.minecraft.launchwrapper.LogWrapper log INFO: Using primary tweak class name cpw.mods.fml.common.launcher.FMLTweaker Feb 16, 2015 10:33:22 PM net.minecraft.launchwrapper.LogWrapper log INFO: Calling tweak class cpw.mods.fml.common.launcher.FMLTweaker 2015-02-16 22:33:22 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.4.49.965 for Minecraft 1.6.4 loading 2015-02-16 22:33:22 [iNFO] [ForgeModLoader] Java is Java HotSpot 64-Bit Server VM, version 1.8.0_25, running on Windows 8.1:amd64:6.3, installed at C:\Users\drape_000\Documents\runtime\jre-x64\1.8.0_25 2015-02-16 22:33:22 [iNFO] [ForgeModLoader] Loading tweak class name cpw.mods.fml.common.launcher.FMLInjectionAndSortingTweaker 2015-02-16 22:33:22 [iNFO] [ForgeModLoader] Loading tweak class name cpw.mods.fml.common.launcher.FMLDeobfTweaker 2015-02-16 22:33:22 [iNFO] [ForgeModLoader] Calling tweak class cpw.mods.fml.common.launcher.FMLInjectionAndSortingTweaker 2015-02-16 22:33:22 [sEVERE] [ForgeModLoader] Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:901) at java.util.ArrayList$Itr.remove(ArrayList.java:865) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:27) Java HotSpot 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release
