I have overhauled the Norwegian language file and updated strings needed to work.

You just click it to open, dump it on your desktop or somewhere convenient.
Then you upload this file (nb-NO.com_comment.ini) through FTP (or something similar) to your sites directory => /language/nb-NO/
Then you go to your frontend again, and press F5 or something to refresh the page, and it's done.
