ERROR: Could not find or load main class


Recommended Posts

I'm trying to figure out how to download Minecraft Forge, and I keep on getting this error "

Error: Could not find or load main class .net.preferIPv4Stack=true

" when I type in "

java -Djava.net.preferIPv4Stack=true -jar forge-1.14.4-28.1.104-installer



Another issue is that it saved as a "Windows Media Player " file instead of whatever it should be, (I'm using a Windows 10 laptop).


Please help! I'm super excited to get this figured out with you guys. :)
