Not the specified path?
Right click on the think you are trying to open and click EDIT.
In it it should say something like: "C:\Program Files\Java\jdk1.6.0_15\bin\javac.exe"
"jdk1.6.0_15" is the bit you will NEED to change. You will need to change it to YOUR JDK version.
To do this go in to Computer >> C: drive >> Program Files >> Java
After Java you should have your JDK Version. If your version is 16, change it to "C:\Program Files\Java\jdk1.6.0_**16**\bin\javac.exe" without the asterisks, and do the same for all of the versions and all of the other things that are saying that.
Hope this helped!
EDIT: If it still wont let you on it, you will need to change that to what your files are named. EG: If your program file is called bananas, you will need to change it to "C:\**Bananas**\Java\jdk1.6.0_16\bin\javac.exe "
