I can't run jar files on my Windows 7 PC

OK, so I can't run Java executable files of any sort on my Windows 7 PC. The one in particular I'm trying to use is the Forge installer for Minecraft. Normally, an installer window should open when I double click the file. I have Java installed and I set it to open with Java (TM) SE Binary but all that does is make the command prompt window open and then close again instantly. I have tried using the command method to open it but then it comes up with the error saying Error:

Unable to access jarfile runable_jar.jar

I have downloaded the JDK file because I heard that was something I needed, but I'm not sure where to put it so it will do what it is supposed to.

Was there something else I needed to download or is there something wrong with the version of Java I'm using (I checked and it's at the latest update). By the way I have a Windows 7 64 bit if that helps.
