Hello all. SOLVED.

Finally using this video (https://www.youtube.com/watch?v=R3Hj83J0ekk), and Changing the value in the first step (I modify it with -XMX8g not delete) and now i start SH3D and i see:

Java version 1.8.0_202 - 64 bit - 0.1 / 7.1 GB


So finally it's working.

thanks a lot to all of us hwo helped me here or with Private Message.

so the problem was, my system was blocking any change of memory in JAVA restricting to 512MB.
