When installing Vision4D, the user is prompted for a variety of preferences, including whether to install the GPU package:

If the computer where the installation takes place is connected to the internet, selecting this option will start the download and installation of the additional components. Users can simply proceed with the installation as normal with no additional action. 

However, if the computer in question is not connected to the internet, this will not be possible. Instead, the GPU package will need to be downloaded and installed independently.

The GPU package is available to download here: https://www.arivis.com/download/arivisVision4D/3.6/DeepLearningGPUSupport. Once downloaded, the EXE file can be copied over to the system where Vision4D has been installed and run to perform the installation.
