[1.12.2] Liteloader won't start in Technic Launcher

[Steve505]

Hey there! I'm trying to install Liteloader to Technic Launcher, but every time I'll get this error: [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/ERROR] [LaunchWrapper]: Unable to launch [B#402] 2019/04/07 10:56:06 [INFO] java.lang.reflect.InvocationTargetException: null [B#402] 2019/04/07 10:56:06 [INFO] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_191] [B#402] 2019/04/07 10:56:06 [INFO] at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_191] [B#402] 2019/04/07 10:56:06 [INFO] at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) ~[?:1.8.0_191] [B#402] 2019/04/07 10:56:06 [INFO] at java.lang.reflect.Method.invoke(Unknown Source) ~[?:1.8.0_191] [B#402] 2019/04/07 10:56:06 [INFO] at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) [launchwrapper-1.12.jar:?] [B#402] 2019/04/07 10:56:06 [INFO] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.12.jar:?] [B#402] 2019/04/07 10:56:06 [INFO] at joptsimple.OptionSet.valueOf(OptionSet.java:179) ~[OptionSet.class:?] [B#402] 2019/04/07 10:56:06 [INFO] at net.minecraft.client.main.Main.main(SourceFile:59) ~[Main.class:?] [B#402] 2019/04/07 10:56:06 [INFO] ... 6 more [B#402] 2019/04/07 10:56:06 [INFO] Exception in thread "main" [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: net.minecraftforge.fml.relauncher.FMLSecurityManager$ExitTrappedException [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraftforge.fml.relauncher.FMLSecurityManager.checkPermission(FMLSecurityManager.java:49) [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: at java.lang.SecurityManager.checkExit(Unknown Source) [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: at java.lang.Runtime.exit(Unknown Source) [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: at java.lang.System.exit(Unknown Source) [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraft.launchwrapper.Launch.launch(Launch.java:138) [B#402] 2019/04/07 10:56:06 [INFO] [10:56:06] [main/INFO] [STDERR]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraft.launchwrapper.Launch.main(Launch.java:28)

This is happening with dropped .jar into mods folder, as well as when I'll edit version.json.
