Chuds Posted November 3, 2018 Share Posted November 3, 2018 (edited) On my desktop I have forge version 1.12.2 - 14.23.5.2772, I tried to install it on my laptop but when I try to open the .exe nothing happens. I have tried opening CMD and executing a command, using different versions, using the universal and regular jar installer with no success. When I try to open the .exe I get a log that contains the following: 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 Edited November 3, 2018 by Chuds Link to comment Share on other sites More sharing options...
ArcticVoid Posted November 3, 2018 Share Posted November 3, 2018 (edited) I am having the same problem, but it seems to be a know issue: Edited November 3, 2018 by ArcticVoid Link to comment Share on other sites More sharing options...
