Launcher not working

This is a general support ticket template.
Please fill in as much detail as possible.

Before Posting:

Java 8 is required to run our modpack. Not having it will cause you to crash on launch.
Mac OS, Windows, and Linux users can download the Java 8 installer for their system from here.


how did you install the modpack?:launcher
have you installed Java 8?: _yes _
when does the problem happen?: _during launch
logs/crash-report: The game is running. Please wait.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Process ended with code: 1

problem:
So I pressed launch on the launcher and after a few seconds it does nothing and it pops up with that crash report.

Looks like you’re running a 32bit version of Java since it can’t run the game at -Xmx4096M, get the 64bit version: http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

Thank you Guan, now it works
