You need to download a program such as 7zip what i use. then you need to right click on your minecraft.jar file open with, browse for program, look for 7zip file manager. use that program to open your minecraft.jar. It will either be in your program files or program files (x86) depending what you download.

I have opened it before with 'Java™ Platform SE binary', but now it has decided not to work, I have done nothing to Java or the Minecraft.jar

Where is this Minecraft.jar?
Supposedly, you're trying to open the core jarfile.
Try using the Launcher.
I used to be a Support Guru, but then ran out of time. I have more time now, but I'll only make the occasional helpful post.

The same kinda thing is happening to me. I need to add some stuff to the .jar for a mod but it comes up with "Java Exception has occurred". Any ideas?

Use 7-zip to open it instead of java runtime.

A suggestion would be to use MagicLauncher to install your mods, but for certain ones you will need to open your minecraft.jar, if this is the case, I have no suggestions other then 7zip. I hope this was helpfull :)

It is happening to me as well and nothing I do will fix it. No mods no texture packs no worlds nothing it is a completly untouched new one but I still get that error. And it is really starting to make me really mad. What did they do to minecraft to make it do this?

You can't open a jar file with Java Runtime Environment, that tries to run the file. You have to use 7-zip or Winrar. It has always been this way.

Hi Guys!
    Same thing happened with me, but I found out how to fix it. For me all I had to do was go into my modded jar and go into META-INF. Once there, delete everything except Manifest.mf. Hope this helps!
