Modpacks thinking I have 32-Bit Java?

[articz82]

For some reason, Attack of the B-Team (I also tested with other modpacks in the Technicpack) think that I have 32-bit Java. Vanilla MC (and every single Java-based program on my computer) recognize the 64-Bit Java that I have installed. I *think* that I am on a 32-Bit browser but I definitely have 64-Bit Java installed. All technic pack servers also do not recognize my 64-Bit Java, so I'm unable to run a server with more than 1G of RAM. Anyone know what is causing this/a fix?

you need to put the path of you 64bit java file in your launch.bat
