- The information about where to get the installer is incorrect. You can download the installer from anywhere it's available.
- You still haven't confirmed your specific goal. Is it to: Install English only on systems that are English and install English and Norwegian on systems that are Norwegian?
- I pointed you to the Admin Guide's troubleshooting section which has a cmd line for this error. Try it and if it fails, post your cmd line and result.
- Have you confirmed you have the right serial? You need one specific to the language(s) you are installing.
