Windows .exe 1.6.4 modpacks won't launch

[sagMC]

Hello everyone!
I've tried launching the monster pack and direwolf20 pack with no success.
It gets stuck on the mojang screnn for about 3 minutes and crashes.
Here is the console log: http://pastebin.com/Dd4YjtKm

Please help!

You have 32-bit Windows 7, and thus limited to 32-bit Java. You're limited to the amount of RAM that you can assign to Java, which is less than what is required to run Monster and DW20 1.6.4.

Try seeing if you can run the FTB Lite 2 pack; it's the only 1.6.4 FTB pack that's designed to run on a 32-bit system. If that too fails to load, please post a fresh console log to pastebin.com.

The other solution is to upgrade your OS to 64-bit Windows 7, and then install 64-bit Java. Then, assuming your system has more RAM to assign, you can assign more RAM through the FTB luancher options to Java.
