[Solved] Cannot Allocate More RAM to Minecraft

[Kritten]

Been at this for a couple of hours. Tried re-installing Java with no avail, Control Panel>Java seems to do nothing when I change it, and when I launch the regular Minecraft launcher trying to allocate more ram with the Xmx Xms arguments, I get this error:

Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size
Picked up _JAVA_OPTIONS: -Xmx512M


Windows 7 OS, JRE 1.8.0_20 + 1.7.0_67 (both 64-bit), and yes, I already tried Googling it.

Also, I built my own computer, so don't expect me to not know what's in it.

EDIT: Here's the pastebin, for any of you interested in it; http://pastebin.com/Dkspakhf

And I did 'java -version' on cmd, and guess what: "Picked up _JAVA_OPTIONS: -Xmx512M" haunted me there too.

[Solved] Someone else figured it out on my other thread.
