System Requirements

Before You Install EthoVision XT

If you ordered a computer from Noldus Information Technology when you purchased EthoVision XT, the software and any internal hardware has already been installed and tested.

If you did not order a computer, you must install EthoVision XT from the MyNoldus portal. See the Welcome Letter for more information.

Prior to installation, please check the packing list to make sure all the components are present. If any of the components listed is missing or damaged, please let us know.

The contents of your package differ for new and existing users:

• If you are a new EthoVision XT user, you received a Software Activation Key.
• If you are upgrading from older versions of EthoVision XT, you received a Software Upgrade Key to upgrade your current license. See Upgrade EthoVision XT.

Operating System

Windows Version

EthoVision XT 19.0 supports Microsoft Windows 11 Pro and was tested with Windows 11 Pro, 64 bits, version 23H2.

EthoVision XT 19 was also installed on Windows 10 Pro, version 22H2 and Windows 11 Pro, version 24H2 for short tests unrelated to the assessment of tracking performance with specific camera configurations. Although no significant issues were reported, Noldus cannot guarantee that the same performance as on Windows 11 can be obtained on these versions when using a specific camera configuration. See Resolution, Frame Rate, and Maximum Trial Duration.

EthoVision XT is not designed for use with the Touch features of Windows.

User Rights

To install EthoVision XT, you must have administrator rights. In other words: either you are the system administrator or you are a member of the Windows group Administrators and have been assigned administrator rights.

We recommend turning off automatic updates for device drivers. See Turn Off Automatic Updates for Device Drivers.

We also recommend not using a comma as a decimal separator in the Windows regional settings. To check the regional settings, in Windows choose Apps > Windows System > Control Panel. Under Clock, Language and Region, click Change date, time or number formats, then click Additional settings.

Language Support

EthoVision XT has also been tested with Cyrillic, Japanese, and Chinese language packs. Like any software package, it remains possible that minor differences in the operating systems of certain local language versions may affect how well the program runs. If you encounter a problem of this sort, please contact Noldus Technical Support.

Windows Update

There have been cases of EthoVision XT trials being interrupted by forced Windows Update. It is not straightforward to prevent unwanted updates during data acquisition, especially in Windows 11. If you plan to do long data acquisition sessions (e.g. 24+ hours), an easy solution is to disconnect the EthoVision XT computer from the network and restart it before starting the new acquisition session.
