Currently a silent install is not supported. The install procedure is very straightforward though: when you download Cube (from the DataMiner landing page, or from dataminer.services) and execute it for the first time, a window opens with an Install button. Clicking the Install button installs DataMiner Cube with the default options. That's it.

I understand a silent install could be interesting though. Feel free to create a new feature request and discuss this with your project manager.

Uninstall can be done silently, with the /Uninstall /Silent options (see this resource document).
