I was trying to install the minecraft 1.15.2 forge installer, which I aqquired through minecraftforge.net and tried to add to the perfectly legal minecraft game. Upon trying to use Java SE binary to open the installer, it gave me this message:
Java Installation Not Completed
There are errors in the following switches
'C:\Users\Lipek\Desktop\forge-1.15.2-31.1.37-installer.jar';.
Check that the commands are valid and try again.
