How to upgrade Java version from 32-bit to 64-bit with latest version already installed for minecraft

[mattme00]

I have recently obtained a modpack on the technic launcher(minecraft modpack installer) only to find it requires more memory then I am already playing with. My system has 10 GB of Ram and on task manager shows its usage to be 1.2 GB. I have plenty of extra RAM, and found the problem to be the minecraft java version which is 32 bit, how do I change it to the 64- bit java? When I try installing the 64-bit it says I already have the latest version.. This is a pretty confusing problem, and I understand many people wont understand my gibberish. But thanks in advanced if you find an answer.

I figured out the answer! I manually installed the Java offline version of 64-bit, and it gave me options up to 10 GB, sorry for asking when it was so simple! THANKS.
