JDownloader not working or installing
I've been using JD for years now and suddenly the program stopped working and refused to open. I then uninstalled JD2 and tried reinstalling, but that gives me an error message and closes immediately.
I have downloaded the installer from multiple sources and tried installing with and without admin rights but nothing seems to make a difference. I'm on windows 10 using JD2, and the only error details JD provides are: org.jdownloader.update.launcher.JDLauncherFailedException: java.lang.NoClassDefFoundError: org/jdownloader/startup/Main at org.jdownloader.update.launcher.SecondLevelLauncher.launchJDownloader(SecondLevelLauncher.java:797) at org.jdownloader.update.launcher.SecondLevelLauncher.init(SecondLevelLauncher.java:562) at org.jdownloader.update.launcher.SecondLevelLauncher.runMain(SecondLevelLauncher.java:331) at org.jdownloader.update.launcher.JDLauncher.main(JDLauncher.java:10) 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 com.exe4j.runtime.LauncherEngine.launch(Unknown Source) at com.exe4j.runtime.WinLauncher.main(Unknown Source) at com.install4j.runtime.launcher.WinLauncher.main(Unknown Source) Caused by: java.lang.NoClassDefFoundError: org/jdownloader/startup/Main at org.jdownloader.update.launcher.SecondLevelLauncher.launchJDownloader(SecondLevelLauncher.java:729) ... 10 more Caused by: java.lang.ClassNotFoundException: org.jdownloader.startup.Main at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 11 more The problem appears Java related but I updated, then uninstalled and reinstalled it, with no change. Any idea what's causing this? |
