Open files of Netbeans 8.2 Version

I have installed the plug-ins mentioned in this guide: https://blogs.apache.org/netbeans/entry/what-s-happened-to-my to be able to open project of Netbeans 8.2 version, but when i start Netbeans 9 a warning comes out:

Warning - could not install some modules: JavaScript2 Kit - The module named org.netbeans.modules.javascript2.requirejs was needed and not found... ... 18 further modules could not be installed due to the above problems.

If i click on "Exit" or "Disable modules and continue" the program crash and it doesn't open.
