  2. Follow the instructions for the installation.

  3. Select the location to save the app to - make sure to consider your use case:

  • For downloading new projects directly from HoloBuilder

    When wanting to download HoloBuilder projects directly from the HoloBuilder platform, the Offline HoloViewer needs to be installed to a location on any of your hard disks the executed application will have write permission to. This is required to download and generate the .holo file.

    E.g. install the app on the desktop or any other similar location.

    IMPORTANT: Do not install the app on the “C:/Program Files/…”

    NOTE: If your PC or Mac does not have enough storage space, you can also connect an external hard drive to install and run the download directly on that drive.

  • To view a shared .holo HoloBuilder project file added to the project folder

    In order to only save a project in the HoloViewer to view, there are no restrictions on where to install the app.

  • To open a shared project via a double click from any location on your PC

    When wanting to use the option to automatically open the .holo file in the viewer upon double-clicking on the .holo file, you will have to do the following:

    1. Enable admin permissions for the software during the installation of the Offline HoloViewer,


    2. manually select the Offline HoloViewer as the application to open the .holo file with when Windows asks which application it should use to open it.


When not downloading any project directly from HoloBuilder, the system does not require admin permissions. The desktop app can be installed anywhere on the PC.
