If all those make use of other files, those can be replaced with newer versions too.I've described in those posts linked - to replace the liveupdate,livereg,and such components of NAV. I'm sure NIS is also modular enough to make the "replace with new files" possible. I just reformated and installed everything. i had to dl about 20 MB of updates for NIS and Norton Antivirus. I would really like to know how i can intergrate those updates. for NIS 2005
