I have just operated Live Update after 1 day of not using my computer and among the ten updates downloaded and installed(approx 10.60 MB or thereabouts total) was "NIS Product Update" requiring a restart. However after immediate restart I still have NIS Version 18.6.0.29 as before. What was this "NIS Product Update" relating to? Was it an amendment to the current version as I can't see that there has been a newer version.
