Unable to allocate RAM larger than 1GB

Hi.

I can't allocate more RAM larger than 1GB. Also, why is there an exclamation point?

you have a 32-bit java installed, which limits the launcher to 1GB RAM max.

you need a 64-bit java to increase it between 1,5 - 3GB

you don't need to uninstall it. Just install a 64-bit. After you done that, start the launcher and go to Launcher Options and towards the Java Settings tab. There you can change which Java the launcher should use

as for uninstalling software, you just need to find the Control Panel

​Can you please teach me how to uninstall my java version and install 64bit? I have a 64bit operating system.
