JDK was not found on the computer for NetBeans 6.5
I would first double-check that you installed the JDK, rather than just the JRE. It's easy to grab the wrong one and not even realize it. Then I'd make sure that your JAVA_HOME environment variable is pointing to your JDK install directory, NOT the bin directory. You may want to add the bin directory to the PATH environment variable, but Netbeans is more likely looking at the JAVA_HOME environment variable.
Do the following steps to resolve the problem
Ensure that the JDK is already installed.
If the installer is on a CD, Copy the EXE file for the Netbeans 6.5.1 installer onto your hard disk.
Note the location of the installer.
Open a Command Prompt running as administrator: Go to Start button > All Programs > Accessories Right click Command Prompt Select Run as administrator
In the Command Prompt use the cd command to change to the directory containing the installer.
Execute the following command to extract the contents of the installer: [Note: You might need to change the name of the installer to match the one you have.]
netbeans-6.5.1-ml-java-windows.exe --extract
Execute the following command to manually execute the installer:
java -jar bundle.jar
You will see rapid scrolling output in the Command Prompt window for a few moments, then the installer window will appear to begin the installation process.
I use the following steps to solve the problem:
First, Make sure
“Run this program in compatibality mode for: Windows XP (Service Pack 3)” and “Run this program as an administrator” are ENABLED.
Run in Command Prompt
C:\Users\{yourusernamehere}\Documents\Downloads\netbeans-6.5-ml-windows.exe –-javahome "C:\Program Files (x86)\Java\jdk1.6.0_18"
