Since I dont have the problem on other versions I will try it on another forum.

Hey. So i want to play a modpack though I have the problem that I cannot install the Forge Version (or any version for Minecraft 1.12.2!!!!) you see in the title. If I try to install it via the Forge .exe I get the message below. If I try it via Curseforge/Overwolf it doesnt work as well. The problem stays either way. The error message that Forge creates when I try to open the Installer: java.net.preferIPv4Stack=true Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.minecraftforge.installer.Java6Gate.main(Java6Gate.java:48) Caused by: java.lang.ExceptionInInitializerError at net.minecraftforge.installer.ClientInstall.getSponsorMessage(ClientInstall.java:401) at net.minecraftforge.installer.InstallerAction.getSponsorMessage(InstallerAction.java:60) at net.minecraftforge.installer.InstallerPanel.updateFilePath(InstallerPanel.java:334) at net.minecraftforge.installer.InstallerPanel.<init>(InstallerPanel.java:315) at net.minecraftforge.installer.SimpleInstaller.launchGui(SimpleInstaller.java:167) at net.minecraftforge.installer.SimpleInstaller.main(SimpleInstaller.java:54) ... 5 more 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) ... 11 more I know that this issue is known, yet I have not found a solution. Of course I tried reinstalling everything, trying different versions and installing new drivers etc. Please note that I can install and use other Forge versions for other Minecraft version but 1.12.2 . I would really appreciate any help.
