I keep getting errors when I try to start modded minecraft through twitch/curse. In this scenario I was trying to launch All The Mods 3, and got this error:

 

Error: Could not find or load main class D:\Program
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0
 

Vanilla minecraft launches fine, as does the technic launcher. Can anyone assist?

Maybe you could try using an earlier version of Java?

Modded minecraft only support Java 8 and MUST be in 32 bits. 

 

Uninstall Java 64bit then install Java 8 32 bit
