The answer is
We managed installation of netbeans 6.8 under windows 8 successfully the following way:
- Don't execute but unzip netbeans-6.8-ml-windows.exe with 7zip (or other unzipper) in an emtpy folder
- execute cmd.exe as administrator
- cd to the folder in which you unzipped the installer
- execute 'java org.netbeans.installer.Installer'
-> installation executes without any errors
I also had the same problem. So I tried by installing a lesser version say jdk1.5 and running the netbeans installation from command prompt as: Linux: netbeans-5_5-linux.bin -is:javahome /usr/jdk/jdk1.5.0_06 Windows: netbeans-5_5-windows.exe -is:javahome "C:\Program Files\Java\jdk1.5.0_06"
Hope it helps
Set JAVA_HOME in environment variable.
set JAVA_HOME to only JDK1.6.0_23 or whatever jdk folder you have. dont include bin folder in path.
This is only due to javahome path missing.
Use the command line below:--
For Windows OS- Open your command prompt
netbeans-6.5.1-windows.exe --javahome "C:\\Program Files\Java\jdk1.5.0"
For Linux OS- Open your Terminal
netbeans-6.5.1-windows.sh --javahome /usr/jdk/jdk1.6.0_04
The problem solved.
Set the JAVA_HOME variable as noted above, but also set the JRE_HOME variable to the Java Runtime Environment folder (example: C:\Program Files (x86)\Java\jdk1.6.0_23\jre )
To set the windows environment variable, right click on My Computer and select "Properties" and choose the "Advanced" tab on older windows versions, or click the "Advanced system settings" link on new versions of windows. Click the "Environment Variables" button and, in the System Variables section, click the "New" button and add the above variable names and enter the appropriate filesystem paths as the values.
After you've installed Netbeans, check the following:
Open C:\Program Files (x86)\NetBeans 6.0.1\etc\netbeans.conf
Change this value to the location of your JDK folder if it isn't set correctly already:
netbeans_jdkhome="C:\Program Files (x86)\Java\jdk1.6.0_23"
