javac.exe is located in C:\Program Files\Java\jdk1.6.0_18\bin how do I tell java thats where it is

Answer 1

You must set the JAVA_HOME environment variable to refer to the top-level folder where java is installed. Right-click "My Computer", Properties, Advanced, Environment Variables. If there's an existing JAVA_HOME variable, then correct it so that its value is

C:\Program Files\Java\jdk1.6.0_18

If there is no existing variable, then create one by using the "New" button. It's up to you whether to do it for the current user or for the system.
