How ?

 

 

 

[Cadiboo]

Your problem is that you aren't using the proper version of java for minecraft.

Minecraft uses Java 8 Update 151 (Java 8u151). In non-modded minecraft java is included inside the application, however with modding this isn't really feasible considering the amount of instances of minecraft etc.

 

Please read this topic to understand how to make your java the right version.

This topic was for a mac user, if your not a mac user the steps are similar, but not the same.

1 there is no forge installed

 

2 @Cadiboo 1 what you are telling has nothing to do with the issue and 2 he is using Java 8u151

Sorry, the only fix I've ever needed was correcting the java version.

If this isn't forge related why is he on the forge forums and not minecraft forums/support?
