How can I set the JDK NetBeans runs on?

I have the older NetBeans 6.7, NetBeans 6.9, and NetBeans 7.0, which used to run on jdk1.6.0_21 and jdk1.6.0_25. Now I've removed those JDKs and only have jdk1.6.0_26 and jdk1.7.0 left, but I still want to keep the older versions of NetBeans, but now when I run them, I get this message:

"Cannot locate java installation in specified jdkhome C:\Program Files (x86)\Java\jdk1.6.0_25
Do you want to try to use default version?"

I tried to find where it's looking for the "jdk1.6.0_25", and updated a few configuration files in "C:\Program Files (x86)\NetBeans 6.7" and "C:\Users\USER.nbi\registry.xml", and yet the message keeps coming. Where and what do I need to change to point it to C:\Program Files (x86)\Java\jdk1.6.0_26?

Where you already have a project in NetBeans and you wish to change the compiler (e.g. from 1.7 to 1.) then you would need to also change the Java source compiler for that project.

Right-click on the project and choose Properties as outlined below:

Java Project Properties

Then check that the project has the necessary source circled below:

Project Source Compiler

Then check that the Java compiler is correct for the project:

In Windows, open cmd.

Go to the directory where your NetBeans file downloaded.

Then run the below command. The JDK path may be different from the path I mentioned.

netbeans-8.2-windows.exe --javahome "C:\Program Files\Java\jdk-9.0.1"
