#### ProCalc and Nexus 2.16

To run ProCalc with Vicon Nexus 2.16, you must install ProCalc 1.2.1 or later.

To generate joint information (ProCalc angles) from combined Nexus-Theia trial data, you must install ProCalc 1.5 or later.

To generate both joint information and kinetics from combined Nexus-Theia trial data, you must install ProCalc 1.6 or later.

Systems supported for Nexus 2

Before you install Vicon Nexus 2.16, note that Nexus captures data only from Vicon systems (including Vicon Valkyrie, Vicon Vero, Vicon Viper, and Vicon Vantage).

> ⚠️ **Note**
> ⚠️ 
> ⚠️ - Although you can use T-Series cameras with Nexus 2.16, this is not supported or tested.
> ⚠️ - If you add Valkyrie cameras to a system that includes T-Series cameras, the T-Series cameras will not work.
> ⚠️ - FLIR cameras are not compatible with T-Series cameras.
> ⚠️ 
> ⚠️ For information on using MX T-Series cameras with Nexus, see the documentation for versions of Nexus earlier than 2.16.

Upgrading Nexus

This section describes functionality that is dependent upon the version of Vicon Nexus that is being upgraded:

- [Upgrading from Nexus 2.7 and earlier](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11607329/Requirements+and+upgrading#261Earlier)
- [Upgrading from earlier versions of Nexus 2](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11607329/Requirements+and+upgrading#EarlierNexus)
- [Upgrading from Nexus 1.x](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11607329/Requirements+and+upgrading#UpgradingFromViconNexus1.x)

> ℹ️ **Note**   
> ℹ️ Although data collected in Nexus 2.16 (ie, .*c3d*  files) can be viewed in earlier releases of Nexus, you cannot reprocess this data (ie, .*x2d*  with .*xcp*  files) in releases earlier than 2.7.

Upgrading from Nexus 2.7 and earlier

Improvements to camera calibration that were provided by Nexus 2.7 have the following effects on compatibility of data between releases:

- Data collected in earlier releases of Nexus can be reprocessed in Nexus 2.16 because calibration (*.xcp*) files that were created in earlier releases are fully compatible with Nexus 2.16. Note that if you load a calibration (*.xcp*) file that was created in an earlier release of Nexus into Nexus 2.16 and save it, Nexus maintains its compatibility with earlier releases.
- You can use earlier releases of Nexus to view data that was collected in Nexus 2.16 (that is, you can open Nexus 2.16 .*c3d* files in Nexus 2.7 and earlier).
- However, calibration (*.xcp*) files that are created in Nexus 2.16 are not backward-compatible, that is, they cannot be read by releases of Nexus earlier than 2.7, and loading will fail if attempted.

#### Upgrading from earlier versions of Nexus 2

If you are upgrading from a previous version of Nexus 2, during installation a dialog box gives you the option of adding the ** Auto Intelligent Gap Fill ** button and/or the **Add to Quick Report** button to your Nexus toolbar. For more information on these features, see [Automatically fill gaps in trial data](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11613642) in the *Vicon Nexus User Guide* and [Quick Reports](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11612002/Menu+bar#QuickReports) in the *Vicon Nexus Reference Guide*. To add the additional button(s) to your toolbar, click **Upgrade Files**.

On first launch, Nexus 2.16 scans the installation directories of earlier versions of Nexus 2 and offers to automatically transfer custom objects that it finds.

If you click **Import Files**, Nexus 2.16 copies custom calibration objects from earlier versions of Nexus (2.0 and later) to the **Public Documents** folder (eg, *C:\Users\Public\Documents\Vicon\Nexus2.x\CalibrationObjects*).

> ⚠️ **Important**   
> ⚠️ When you create new custom calibration objects, ensure you save them into this folder (not to the Nexus installation folder), so that they are available to future versions of Nexus.

Upgrading from Nexus 1.x

> ℹ️ **Note**   
> ℹ️ This section applies only to versions of Nexus that are earlier than 2.0.

Nexus 2.16 installs into its own folder, called *Nexus2.16*. If you already have Nexus 1.x installed, it will remain installed alongside the new Nexus installation.

On installation, Nexus 2.16 automatically scans for Nexus 1.x files, displays a list of any older files that it finds, and provides an automated system for importing these into Nexus 2.16.

![image](media://ca70feba-06ec-4938-94b5-e364fa49d5e0)

This process copies all the old files and converts the copies, ensuring that original files are not moved, altered, or destroyed.

For more information on the installation and licensing process, see [*Installing and licensing Vicon Nexus*](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11605652).
