Yes, I have updated java, and uninstalled and reinstalled it. I've tried it on 1.18.1 and 1.12.2. My antivirus is off (Windows defender) This is the error

No matter what I try I cannot get forge 1.7.10 to install. I've tried the windows installer, which will not open unless I disconnect my wifi and if I do it that way I get this error. "These libraries failed to download. Try again. org.scala-lang.plugins:scala-continuations-library_2.11:1.0.2 org.scala-lang.plugins:scala-continuations-plugin_2.11:1.0.2" When I try it with my wifi connected it doesn't do anything and creates a log saying this "Exception in thread "main" java.lang.ExceptionInInitializerError at net.minecraftforge.installer.ClientInstall.getSponsorMessage(ClientInstall.java:326) at net.minecraftforge.installer.InstallerAction.getSponsorMessage(InstallerAction.java:59) at net.minecraftforge.installer.InstallerPanel.updateFilePath(InstallerPanel.java:236) at net.minecraftforge.installer.InstallerPanel.<init>(InstallerPanel.java:217) at net.minecraftforge.installer.SimpleInstaller.launchGui(SimpleInstaller.java:153) at net.minecraftforge.installer.SimpleInstaller.main(SimpleInstaller.java:40) Caused by: java.lang.ArrayIndexOutOfBoundsException: 1 at net.minecraftforge.installer.MirrorData.buildMirrorList(MirrorData.java:84) at net.minecraftforge.installer.MirrorData.<init>(MirrorData.java:63) at net.minecraftforge.installer.MirrorData.<clinit>(MirrorData.java:17) ... 6 more " If I try to open the jar, it just doesnt do anything. If I use the method for running the jar via powershell, I get this error. "PS D:\Downloads> java -Djava.net.preferIPv4Stack=true -jar 1.7.10 Error: Could not find or load main class .net.preferIPv4Stack=true Caused by: java.lang.ClassNotFoundException: /net/preferIPv4Stack=true" I've tried installing an older version of java and still it doesnt work. PLEASE HELP. I really want to play a certain 1.7.10 mod
