Naviate for Revit 2019 has the following prerequisites:
Download and unzip the installation files from your account on www.naviate.com. You should have either an MSI file with an associated CAB data file, or a single MSP file for hotfixes/minor updates.
There are four types of licensing for the Naviate products - trial, rental, local and network. If you are using the 30-day trial you can skip this section and go directly to the next.
Rental, Local (SLM) or network (NLM) licenses all require license numbers. When ordering any of the licensed Naviate products your will receive an e-mail with your unique license number(s), automatically sent from our license system.
If you have ordered network licenses you will need to set up a license server service on one of the servers in your local network.
A local license authorizes a single user to install and use the specified Naviate product on a single computer. See Software License Agreements for information specific to your software.
Local licensing allows you to use your Naviate product in trial mode for a specified period, usually 30 days, from the first time you start the product. You can activate your license at any time before or after the trial period expires.
A network license allows a number of users on the same TCP/IP network to share access to product licenses. The Network License Manager (NLM), installed on one or more servers, controls the distribution of licenses to users.
When you start a feauture in a Naviate product, it requests a license from the license server through the network. If a license is available, NLM assigns a license to the computer, and the number of available licenses on the license server is reduced by one.
When you exit a product, the license returns to the NLM.
