1.12 Forge cannot install:

[ChorneTheFirstborn]

I've tried downloading different versions: Not just the recommended and latest but various other random versions.

I've tried downloading the .jar file and tried using the command 'java -Djava.net.preferIPv4Stack=true -jar' in Powershell. I got the error message 'Error: Could not find or load main class .net.preferIPv4Stack=true'

Every time I try installing, it says it can't download a certain file, ( maven.artifact ), and stops.

I have the log for the installer as well, I attached it.

Can I get some assistance with this, please? I would greatly appreciate it.

Post the exact command you are running because if you ran the one given to you in the EAQ you wouldnt get that error.

That's what happens when you try to run that command with PowerShell, you need to use CMD. (You can run CMD inside a PowerShell window by typing cmd)

I used "java -Djava.net.preferIPv4Stack=true -jar forge-1.12-14.21.1.2387-installer.jar".

 

And pardon me, I'm unfamiliar to Powershell... how exactly do I input 'cmd)'? I think I'm doing it wrong. I keep getting an error message:

I typed it correctly, ( I think, ) got this error message:

It worked! That was what was doing it.

Thank you all for your time.
