To start using Vicon Nexus, you must first request a license and activate it. You may also need to set the license server for your license. If you want to use Vicon Nexus remotely, you will need to set up commuter licensing. For details of these procedures, see the following topics:

Move and revoke Vicon Nexus licenses (including commuter licensing)

Request a license

To request a license, you start Vicon Nexus and supply the relevant details.

To request a license from Vicon Support:

If you are using a SafeNet dongle to license your machine:
1. Ensure you have installed the latest dongle drivers onto the PC on which you will run Vicon Nexus. You can either choose the option for dongle drivers when you install Vicon Nexus, or run the Vicon Nexus installer at any time, or you can download the drivers from the Downloads page on the Vicon website.
2. Insert the dongle.
On the machine for which you want the license (either a networked license server or a standalone machine), start Vicon Nexus and at the left of the dialog box, click Request License.
Note: You can also manage licensing in the following ways:
- After you have licensed Vicon Nexus, start Nexus and on the Help menu, click Vicon Product Licensing; or
- To run the Vicon Automated Unified Licensing Tool (VAULT) independently of Vicon Nexus, click the Start button, then All Programs > Vicon > Licensing > ViconProductLicensing.
At the top of the Request a License dialog box, from the Product and Product Version menus, ensure Vicon Nexus and 2.x are selected.
In the appropriate fields, type your name, email address and company name.
In the Options area, select whether to request:
- Standalone license locked to local PC name: for use by the PC from which you are sending this request only
- Network license locked to license server name: for use on the license server machine from which you are sending this request by one or more PCs on the same network
- Standalone license locked to a dongle: for use with the specified dongle on a single PC. In the Dongle ID field, type the ID, which is found on the dongle
For network/server based licenses only: if necessary, change the value for the Number of Seats.
Leave the settings in the Machine area at their default values unless you are asked to change them by Vicon Support (for example, if you are using a dual-booting system or have had to reinstall Windows).
Do one of the following:
- If you can currently email your license request, click the Email Request button; or
- If email is currently unavailable, click Save Request to a file, so that you can send the request later. Type or browse to a suitable location and click OK. The file is saved as ViconLicenseRequest*.xml. When possible, email the file to Vicon Support.

Activate a license

After you have received a license file from Vicon Support, you must activate it before you can start using Vicon Nexus.

To activate a license:

Check your email for a message from Vicon Support. The license file (named Vicon Nexus Release Number License Type.lic, for example, Vicon Nexus 2.12 Network.lic) is attached to the email. If you are using a Safenet dongle, the email has the ID of your dongle (of the form UBnnnnnn) in the Subject line.
If you have not received a license file, request one as described in Request a license.
Save the license file (*.lic) to the Windows desktop of the machine for which you have a license (or any other suitable location).
Start Vicon Nexus and in the Vicon Automated Unified Licensing Tool dialog box, click Activate License.
Depending on whether you are using the file as it was received from Vicon Support or as a text string copied from the file:
- In the License File Activation field, type or browse to the location of the license file (.lic) and click *Activate from File; or
- Copy the text to the License Activation string field and click Activate from String.
Click OK.

Tip
You can deactivate a network license from the relevant license server machine only, not from any of the client machines.

When you have activated your license, you are ready to start using Vicon Nexus.

Set the license server

If a server provides licenses to client PCs on your network, to enable a client PC to find its license quickly, on the client PC specify the license server for Vicon Nexus to use.

If you use standalone licensing, Vicon Nexus should find its license. If not, or if you need to change the license server, complete the following steps.

To enable Vicon Nexus to find its license:

Ensure you have installed Vicon Nexus as described in Install Vicon Nexus. Depending on the type of license you have, ensure that your system is ready:
- If your PC obtains its license from a license server, ensure that Vicon Nexus is licensed on the relevant server.
- If you are using a standalone license, ensure that you have requested, saved and activated your license on this machine.
Start Vicon Nexus and depending on whether or not a license is found:
- If the Vicon Automated Unified Licensing Tool dialog box opens, click Set License Server; or
- If Vicon Nexus opens and you want to view or change the current license server:
  1. On the Help menu, click Licensing.
  2. In the Vicon Automated Unified Licensing Tool dialog box, go to the Product License Location list (in the lower half of the dialog box), and right-click on the line that shows the relevant Vicon Nexus license and then click Set License Type.
In the Change License Server dialog box, do one of the following:
- To use standalone licensing, select Use Standalone/Commuter Licenses Only and then click OK.
- To obtain a license from any available license server (local or on a network), select Use Standalone/Commuter Licenses Or Scan for a License Server and then click OK.
- To select a specific license server from a list of available servers:
  1. Click Discover. Local and network licenses are displayed.
  2. In the Available Servers list, double-click the required license server and then click OK.
- To specify a license server on your network, select Use a Specific Network License Server, type the name in the License Server field, and click OK.

Tip
You can instead select the required license server by going to the License Server list (in the upper half of the Vicon Automated Unified Licensing Tool dialog box), right-clicking on the line that shows the relevant Vicon Nexus license and then clicking Use This License for Vicon Nexus.

View information about license servers

In the Vicon Automated Unified Licensing Tool dialog box, you can view information about all available license servers without affecting the license server that is currently in use. To do this:

Open the advanced Vicon Automated Unified Licensing Tool dialog box by doing one of the following:
- Before licensing Vicon Nexus, start Nexus and in the Vicon Automated Unified Licensing Tool dialog box click Advanced Licensing; or
- After Vicon Nexus is licensed, start Vicon Nexus and on the Help menu, click Licensing to open the Vicon Automated Unified Licensing Tool dialog box; or
- Click the Windows Start button, then All Programs > Vicon > Licensing > ViconProductLicensing.
In the Vicon Automated Unified Licensing Tool dialog box, if the required license server is not displayed in the License Server field at the top, click Change at the top right of the dialog box.
In the Options area of the Select License Server dialog box, do one of the following:
- To view local standalone licenses and commuter licenses (for information on commuter licenses, see Use commuter licenses), select View Licenses from the Locally Installed License Server; or
- To view licenses on a specified license server, type the required server name in the License Server field. If you don't know the name of the license server, click Discover and in the Available Servers list, double-click a license server.
Click OK.
In License Server list at the top of the Vicon Automated Unified Licensing Tool dialog box, licenses from the specified license server are displayed.

Tip
Changing the license server that is displayed in the License Server list does not affect the license server that is used for licensing, shown in the Product License Location list in the lower part of the dialog box. To change the license server that is used for licensing, see Set the license server.
