he says he does have java 64 bit, and he has 4 GB of ram available on his computer. I'll have him try lowering the number later though, just in case.

We have bumped the ram up to 1548 MB, and now during the mojang screen, a popup appears saying something along the lines of "could not create JMV". He says the forge log has not updated. Any other solutions? Also, please respond ASAP.

Sorry for not getting that right away, here it is:

I'm trying to help my friend start a custom mod pack (Version 1.6.4) we built. Every time, something goes wrong. If we start minecraft using -Xmx1024M as an argument, minecraft starts just fine, but trying to start up a world causes it to immediately say Shutting down internal server, then the game crashes. If we use the -XX:MaxPermSize as an argument, the game throws a "Java has run out of memory" screen, regardless of how much ram is given. (On my end, I was able to run with as little as 1Gb) This problem is local only to him, as I run the exact same mod pack with it just fine (Although I have to use the -XX method and the -Xmx method causes a similar problem.) We have tried everything possible, and nothing helps. What can we do? A list of the mods we are using: The last bit of the console: My friend could not get the forge error log, but I can have him get it if a solution can't be obtained with out it.
