Help with Minecraft.jar

[Master1.0]

Okay, so I need some help opening my minecraft.jar.

Whenever I try to open it, it tells me it failed to load.


Here I am casually trying to open the jar file.


And here I am failing to open it.

I use .zip files, and it would be nice If I could know how to install WinRAR. From what I heard I need that to open the .jar, yet knowing me, I have no idea how to install it.

Install it, then make sure that WinRAR is the default program for opening .jar files.

7Zip is antoher one you can use, it's a simple program that I tend to use. Either this or WinRAR works.
