Windows .jar 1.6.4 packs "Cannot create JVM"

[fusiomax]

Operating System and bit type: Windows 7 32bit
Java version/update and bit type: 7r45 32bit
Launcher version: 1.3.3
Console log, pastebin.com link: http://pastebin.com/SjSnX7JE
Description of the Issue:

Launch's Direwolf20 1.6.4 pack, says it cannot create the JVM and opens nothing.

We have tried reinstalling Java, we have used the Jar and the exe and both have had the same issue, Vanilla Minecraft works, FTB Ultimate 1.5.2 works, but all of the 1.6.4 packs do not work.

Any and all help would be much appreciated, if there is any information I have missed let me know and I will pop it up asap.

Thank you in advance

Your instance can't reserve enough space for object heap. Try adding -XX:MaxHeapSize=256m (also try changing this number a bit). And make sure that your Heap isn't too big on 32 bit windows.

Right, where do I do that?

Under the options tab in the FTB launcher, there is a big button "Advanced Settings". In that window there is a box labeled "Additional Java Parameters" Just copy paste -XX:MaxHeapSize=256m into there.
