From NUITEQ’s collaborative software version 4.10 (release the 25th of January 2016) and onward, you can easily update using its Updater. You can find it in the start menu in your operating system under NUITEQ. Or it can be found in a folder named "update" in the installation location. When you start the Updater, it immediately checks if there is a newer version available for download. If there is, you can simply click the UPDATE button and the Updater automatically takes care of the rest.
Once the update is completed you can safely close the Updater.
If the update is aborted or fails for some reason, the Updater will automatically revert back to your previous NUITEQ’s collaborative software installation. This is to ensure you will always have a working NUITEQ version.
