We really wanted to stick to 1.6.4 if we could. Is that the only way she can run forge?

so, i used the installer to put forge on the gf's laptop...but its not working at all. when i try to run the forge profile the launcher runs for minecraft, i press play, the launcher closes and nothing happens past that. i have no clue whats happening as i have not had this problem before. she has windows 8.1 and im trying to run it on minecraft 1.6.4. the version im trying to install is 9.11.1.965 this is the forge log since the is at this point no crash log for minecraft itself. 2014-11-02 01:35:34 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.4.49.965 for Minecraft 1.6.4 loading 2014-11-02 01:35:34 [iNFO] [ForgeModLoader] Java is Java HotSpot Client VM, version 1.8.0_25, running on Windows 8.1:x86:6.3, installed at C:\Program Files (x86)\Java\jre1.8.0_25 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Java classpath at launch is C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\net\minecraftforge\minecraftforge\9.11.1.965\minecraftforge-9.11.1.965.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\net\minecraft\launchwrapper\1.8\launchwrapper-1.8.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\ow2\asm\asm-all\4.1\asm-all-4.1.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\scala-lang\scala-library\2.10.2\scala-library-2.10.2.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\scala-lang\scala-compiler\2.10.2\scala-compiler-2.10.2.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\lzma\lzma\0.0.1\lzma-0.0.1.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\net\sf\jopt-simple\jopt-simple\4.5\jopt-simple-4.5.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\paulscode\codecjorbis\20101023\codecjorbis-20101023.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\paulscode\codecwav\20101023\codecwav-20101023.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\paulscode\libraryjavasound\20101123\libraryjavasound-20101123.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\paulscode\librarylwjglopenal\20100824\librarylwjglopenal-20100824.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\paulscode\soundsystem\20120107\soundsystem-20120107.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\argo\argo\2.25_fixed\argo-2.25_fixed.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\bouncycastle\bcprov-jdk15on\1.47\bcprov-jdk15on-1.47.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\google\guava\guava\14.0\guava-14.0.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\apache\commons\commons-lang3\3.1\commons-lang3-3.1.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\commons-io\commons-io\2.4\commons-io-2.4.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\net\java\jinput\jinput\2.0.5\jinput-2.0.5.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\net\java\jutils\jutils\1.0.0\jutils-1.0.0.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\com\google\code\gson\gson\2.2.2\gson-2.2.2.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\lwjgl\lwjgl\lwjgl\2.9.0\lwjgl-2.9.0.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\libraries\org\lwjgl\lwjgl\lwjgl_util\2.9.0\lwjgl_util-2.9.0.jar;C:\Users\Valerie\AppData\Roaming\.minecraft\versions\forge\forge.jar 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Java library path at launch is C:\Users\Valerie\AppData\Roaming\.minecraft\versions\forge\forge-natives-12442474460295 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Enabling runtime deobfuscation 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Instantiating coremod class FMLCorePlugin 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Enqueued coremod FMLCorePlugin 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Instantiating coremod class FMLForgePlugin 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Enqueued coremod FMLForgePlugin 2014-11-02 01:35:34 [FINE] [ForgeModLoader] All fundamental core mods are successfully located 2014-11-02 01:35:34 [FINE] [ForgeModLoader] Discovering coremods 2014-11-02 01:35:34 [iNFO] [ForgeModLoader] Loading tweak class name cpw.mods.fml.common.launcher.FMLInjectionAndSortingTweaker 2014-11-02 01:35:34 [iNFO] [ForgeModLoader] Loading tweak class name cpw.mods.fml.common.launcher.FMLDeobfTweaker 2014-11-02 01:35:34 [iNFO] [ForgeModLoader] Calling tweak class cpw.mods.fml.common.launcher.FMLInjectionAndSortingTweaker 2014-11-02 01:35:34 [sEVERE] [ForgeModLoader] Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(Unknown Source) at java.util.ArrayList$Itr.remove(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:27) thank you for your consideration and hard work and hope to hear from someone soon.
