In order to view downloaded HoloBuilder projects, you will need to have the Offline HoloViewer installed on your computer.

The offline HoloViewer is available for Windows and Mac devices.

Downloading the HoloViewer

Before downloading any projects yourself or viewing any shared offline projects, you should make sure to download and install the Offline HoloViewer to your computer:

1. Go to the HoloBuilder website.

2. Navigate to the Downloads section and find the download options for the HoloViewer.

Please note that if you are on the EU server solution, please download our EU Offline HoloViewer.

3. You can choose the appropriate download option for your computer - currently, the HoloViewer desktop app is available for Windows as well as Mac users. 

Click the correct download option and the HoloViewer will be downloaded to your computer.

  1. Save the download file.
  2. Follow the installation instructions.

4. Once the Offline HoloViewer was installed, you can either proceed by downloading projects from your dashboard or Web Editor account or open a shared offline HoloBuilder project to view.

Double Click Option for opening a project in the HoloViewer

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:

  1. enable admin permissions for the software during the installation of the Offline HoloViewer.
    OR
  2. manually select the Offline HoloViewer as the application to open the .holo file with when windows ask 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. 


When wanting to download HoloBuilder projects directly from the HolBuilder 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 location than “C:/Program Files/…”
