JDK was not found on the computer for NetBeans

I was facing the same problem, not it works fine.

1. just open cmd
2. cd to the directory where your netbeans setup file is located.
3. in cmd, write the name of the entire setup file and write --javahome "address of jdk"
4. hit enter, it will surely solve your problem

for example, if the setup file is: netbeans8.02.exe

and path of JDK is C:/program files/java/jdk9.01

then run the command:

netbeans8.02.exe --javahome "C:/program files/java/jdk9.01"

and hit enter! :-)
