You have -Xmx256M in the _JAVA_OPTIONS variable in your environment settings, To remedy this,

1. Uninstall Razer Synapse / Cortex if you have it
2. Press the Windows key and the Pause/Break key simultaneously
3. A window should popup, click on "Advanced system settings"
4. Click on "Environment Variables"
5. Delete the _JAVA_OPTIONS entry
6. Restart the computer.

There is no java options entry.

I have continued to search, and yet there is no _JAVA_OPTIONS variable in my environment settings. What should I do?
