C:\Tekkit servers\Tekkit_Server_3.1.2>java -Xmx=4G -Xms4G -jar Tekkit.jar nogui
Invalid maximum heap size: -Xmx=4G
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I have tried uninstalling old versions of java and downloading the latest x64 java 8 to no avail.
I'm running 16 gigs of ddr4 memory so the 4 should be a breeze.
FIXED
After an hour of fumbling i realized i needed to drop "=" from the Xmx line. Sorry to waste anyones time.
