Details of the issue:

Ran into an Java.lang.outofmemory heap error when starting the Launcher. After reinstalling both Java and the Launcher and changing the Java runtime parameters to higher values (4G) i now run into an Java gc overhead limit error​

Have you tried allocating more memory?

Tried it with the General Java-Options as well as starting the Launcher via a batch-file with the corresponding commands. When i try it with the batch-file, the Command-Box says:
C:\xxx\xxx>java -Xms4G -Xmx4G -jar FTB_Launcher.jar
picked up _JAVA_OPTIONS: -Xmx12M
Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size


I have no idea were it gets the Xmx12M from as i set the general Java runtime parameters to -Xms4G -Xmx4G also...

You need to unset environment variable called _JAVA_OPTIONS in .bat or remove it from your computer.

I don´t no where this variable is coming from and can´t find it. Can you tell me, how unset it?
