Minecraft Forums

Same goes to Lite Loader, nothing is working but the Vanilla version of the game.

I installed Java 9 (which improves my performence by 20023130193012%)

And since then my Forge just won't open. I tried to install the previous version I had and Forge still won't work. there is no crash report or anything, do you know whats going on? thanks!

Did you read the whole post? I said already there are no crash reports and no logs that will help.

AND google Java 9, it improves my performence by ... I don't know how much but alot. (I'm playing on my old computer with poor CPU and GPU, I get 400+- FPS on 6 chunks.)

I press PLAY and nothing happens. that's all. NO CRASH REPORTS.

Only now I got a single log after 1 billion tries trying to open Minecarft with Forge.

Launcher log located at .minecraft\logs right? if so this is the only thing I got.

Thanks, fixed my issue.

Huge hypes for Java 9 once it's finished, 200% more FPS then now. I want to know my FPS once I will fix my gaming computer.. (GTX 780 & i7 Extreme <3)

Came up with a new issue trying to open Minecraft itself.

I played normally on the Forge version for few mins, I closed minecraft to install the mods again but when I tryed to launch minecraft launcher ITSELF it just won't open? no error massage and javaw.exe or somesort in the Task manager, no nothing? weird.

Deleted Java again (x2). getting this issue when trying to launch Minecarft: The registry refers to a nonexistent Java Runtime Environment installation or the runtime is corrupted.


Getting issue while installing Java. wth is going on..

-_-..

Alright. the 7th version of Java won't install correctley on my computer so I installed Java 9 instead and it fixed, I guess I will play Vanilla for some time.

Not sure what to do.. should I try and install Java 8?
