NNM 5.9.0 for Windows Vista, Server 2008, Server 2012, Server 2016, 7, 8 and 10 (64-bit)
NNM 5.9.0 for macOS 10.9 - 10.13 (64-bit)
The NNM Web Server version 2.5.0 is a required upgrade for all versions of NNM prior to 5.9.0. It is included in the installers for NNM 5.9.0 and is only necessary as a download for prior versions of NNM to remediate an issue that select NNMs connected to IS or Tenable.io may have experienced if the new web server was not automatically downloaded during normal updates. If plugin updates are no longer working on your copy of NNM and the version of your NNM's web server is not 2.5.0 or later, copy this file to /var/nnm/scripts/ and restart NNM. See the NNM 5.9.0 user manual for more information.
