I have the following problem when I try to install forge for 1.12.2 I get the following error message
Java can't be installed
There are errors in the following switches:
C: \ User \ Jarod \ Desktop \ forge-1.12.2-14.23.5.2847-installer.jar
Make sure the commands are valid and try again
I would try to install Forge with the Windows installer instead of the installer. You should also use the Recommended Version (Right), as the Latest Version (Left) is often incorrect.
