GUI
GUI Note: Your browser may also come up with a warning, and you will need to choose "Keep Anyway" from the download prompt.
GUI Choose Components: Keep all components checked (recommended), can uncheck "Vizard 8" if Vizard is already installed (or other programs you may already have, such as Ollama).

This may also include the "E-Learning Lab" add-on if available.
GUI Enter License Key: Enter your license key. If you do not have a key, SightLab will run in Demo Mode.
GUI Select Projects Folder: Choose a folder to store your Projects and Example Scripts (Note: In older installers this may come up behind the installer. If the installer seems to stop responding, check this window is not waiting in the back). Click "close" when done.
GUI Continue to Next Step: Click OK to continue. The installer will check for an existing Vizard installation. SightLab supports both Vizard 7 and Vizard 8. If no Vizard 8 installation is detected, you’ll be prompted to install it. Note: In the latest installer, this step is automatic — no need to click OK manually.
GUI Install Core Package: The SightLab Core Package and Resources will install automatically (SightLab Core in your Vizard python packages and Resources into C:\Program Files\WorldViz\Sightlab2)
GUI Multi-User: If installing the Multi-User version will need to choose the location of your Project folder. The default location is C:\Users\UserName\Documents\Sightlab2. Note: With the latest installer this step automatically finds the location.
GUI Finish Installation: Click Close to complete the installation.
GUI Close Ollama (if installed): The latest installer includes Ollama for the AI interactions. You can close the Ollama interface after installation as it stays open by default and is not needed.

Note: The latest installer includes K-Lite Codec Pack, if using an earlier installer, it is recommended to download the K-Lite Codec Pack for video playback, especially if recently upgraded from Windows 10 to 11 (an alternative is FFDShow as well).
