Problem compiling from command line

I am having problems compiling HelloWorld.java.

I have added C:\Program Files (x86)\Java\jdk1.6.0_24\bin to my Path, but I still get the error: "'javac' is not recognized as an internal or external command, operable program or batch file" when I type "javac HelloWorld.java" from C:\Users\Steve\Desktop\Java (where HelloWorld.java is saved).

I then tried it this way:

C:> "C:\Program Files (x86)\Java\jdk1.6.0_24\bin\javac" HelloWorld.java and it says "Access is denied".

I can't figure out why it just refuses to work, can anyone help me out?

Make sure you open a new command line window after changing your environment variables.

If that doesn't work, try following this tutorial, when I first started I used it and it helped me out quite a bit.

The first one installs it and sets the path, I believe the second one creates a hello world program and runs it.

I did open a new command line window and it still didn't work.

I will try the tutorial, thanks!
