Hello, i have the same problem, but yesterday i downloaded it and it worked, than i installed a modpack and try to run it, but Java stopped every time. After this i updatet Java to the newest version (i think it was 32 bit, but now it is 64 bit) and Minecraft is still working but now i got the same problem with the technic launcher. Im using MSI Afterburner to control my GPU Fans and my question is: Can i disable/remove RTSS without complications?
