Posted August 31, 201411 yr Every time I start my modded server (since I've upgraded to Forge 10.13.0.1208), I've been experiencing the following error: [11:41:33] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.co mmon.launcher.FMLInjectionAndSortingTweaker [11:41:33] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.co mmon.launcher.FMLTweaker [11:41:33] [main/ERROR] [LaunchWrapper]: Unable to launch java.lang.RuntimeException: FML was unable to install the security manager.

August 31, 201411 yr Can we have your launcher log? Read the EAQ before posting! OR ELSE! This isn't building better software, its trying to grab a place in the commit list of a highly visible github project. www.forgeessentials.com Don't PM me, I don't check this account unless I have to.
September 4, 201411 yr However you are running minecraft is adding its own security manager to java, this is not supported. You should run minecraft normally. I do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon
