So when I went for the blank spot it did not have the option to open command. however I did get the command prompt to open and I followed your instructions. It failed.
here is the results of your second request
java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) Client VM (build 25.241-b07, mixed mode)
I have Minecraft 1.15.2. I downloaded the appropriate forge version and made sure my Java is up-to-date. Every time I launch the installer all that happens is a window pops up, there is black in the screen, and then closes. Please let me know what I am doing wrong. Thank you for your time.
