Well, it's just like the title said: When I install Forge, it brings up a dialog box saying that Forge was successfully installed. Which it wasn't. When I try to start a game with the profile "Forge" selected, the game does not start.

When I keep the launcher open and look in developer console, I find this:

You have one or more mods installed that is messing up the startop. Make sure you clean your mods folder.

Also post the full log from the logs folder.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

You have Java 8, I had the EXACT same issues.

 

Lex, this was the same issue I brought to you.  I think Forge is NOT compatible with java 8.

 

Uninstall Java and then download the most recent version from their website, I believe it is currently 7.55

Forge 1.6.4 isn't compatible with java 7. Upgrade to forge 1.7.2 if you want use java 8.

Also you can install java 7 and java 8 in your computer, and force the use of java 7 as follows:

1.7.2 is not compatible with Java 8 either as I had the same issues.  Downgrading to Java 7 fixed the issue for me.

Forge and MC ARE compatible with 1.8.

I have 1/2 a dozen versions of java installed on my machine to test with.

So something in your setup is causing issues.

What EXACTLY do you have installed beyond Forge.

Post your complete minecraft folder.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Lex, I'm not trying to piss you off, but I've only been on the forum for a week and already three different people other than me had the same issue:

Fresh install of MC

Fresh install of Forge.

 

Only issue:  Java 8.

 

Downgrading to 7 fixed the issue for all of us so far.
