[SOLVED]Nothing happens after installing the forge 1.7.10

[lengkaikai]

I have just installed the forge and tried to click the play button but there is nothing happening. It just automatically shut off my minecraft. I tried to reinstall but the same thing happened. Can someone help me with this problem please? Will this related to my Java? I use Java 8.

I wonder if there is anything that you could give us that tells us what is going on...

A record of some kind that keeps track of everything that is happening when you click the play button.

Perhaps a text of some kind that all errors and data is added to that us developers could use to determine issues...

Are you as much an asshole IRL as you are online?  Forge is great, tho...so if being an ass helps you deal...keep doin your thing

This is with Forge 1.7.2, but I get the same problem, so this log may help. fml-client-latest.log contains the following:

My game crashes on trying 1.7.10 because this computer cannot turn off Hardware Acceleration and I don't have OpenGL 2.1, and this crash occurs with both Recommended and Latest versions of Forge for 1.7.2; is Java 8 not supported?

[loordgek]

yes java 8 is not supported

update MC

or downgrade java to 7

[shieldbug1]

Java 8 is supported and has been for at least a month. Update your forge.

[Chibill]

Its not supported Minecraft AND forge are compiled with java 6 so if something from java 6 was removed that is used in forge yeah downgrade your java.

[LexManos]

Jesus christ people stop posting stupid shit.

Java is backwards compatible, they did break something in the update.

We fixed it months ago so it works fine now.

So simple, UPDATE FORGE.

Also if you dont like me being sarcastic to you, READ THE EAQs or you know the big red letters at the top of every page on the forum.

[lengkaikai]

oh i thanks a lot of you by answering my stupid question, I will try and see if it works!

[lengkaikai]

Guys, I try to degrade my java 8 to 7 and it works! Thanks so much!

[LostGirl3434]

how to degrade it

[GotoLink]

UPDATE FORGE.

[LexManos]

You dont, either update Forge or use the fix in the EAQs.
