What is the installer everyone says needs to be used for 1.6.1 forge installation, where do you get it, and how do you use it?

After downloading it, you run it.

If you can't figure out what to do once its ran.. then I feel sorry for you... Its one of the simplest things you will ever see.

Thanks, but how do you execute a .jar file?

You should know how to do it, they are java's equivalent of exe.

How does all that make sense? I don't even understand it.

All programs need to be loaded by SOMETHING to be run.

Executables are loaded by windows.

Jars are loaded by java.

They are in essence, the same thing.

A book is still a book even if one is written in English and the other is in Sweedish.

So what form of Java is required to load a .jar file?

The java runtime environment.

Same java that you need for Minecraft.

The launcher you use for Minecraft is a jar file

Just wrapped in a small exe that does 'java -jar Minecraft.exe'

 

Seriously, how do you not know how to run jar files? They are used in thousands of moden applications.

Either way this is nothing to do with Forge.
