To publish a lesson as an executable file (so a user running it doesn't need Vizard and SightLab installed), follow these steps:
Under options, turn off "AI Agent Assistance" and "Speech Recognition" (as these do not currently work with exes for the E-Learning Lab
Choose the Project in the E-Learning Lab and run it once.
Next, find the file E_Learning_Lab_Single_Publish.py in the E-Learning Lab folder and open this in the Vizard application
In Vizard choose File- Publish as exe (Note it may take a bit of time to finish)
When it is done you will have an exe file in the same folder, which you can rename and send out to other users.
