Desginer Wont Launch After Designer Memory Upgrade

when I upgrade the Available designer memory in gateway settings to anything other than 1 GB, once I launch the client I get the java screen popup and then after a few seconds closes and the designer doesn’t launch. I am running ignition version 7.9.0 64 bits, with java version 8.0_111 64 bits. I have tried restarting my computer and gateways with no change. is there another setting I need to change also for the change to take effect?

Are you sure you don’t also have the 32 bit java installed?

I’ve deleted my 32 Bit Java and the designer launches fine. but I’ve set my maximum memory to 4 GB and the bottom right corner of the designer still says 910mb. I’ve restarted my gateway and PC with the same result.
