Nis2009 16.7.2

I’m working with NIS2009 version 16.5.0 (Help Info of NIS2009). SUMo software update checker says I’m working with 16.2.0 and that there is a new version 16.7.2. What do I have to do? How can I get the new version. I made several update en restarted the computer but it doesn’t work.
