Since you don't need a Zoom account to join a meeting , the easiest way to get your grandparents into the family Zoom is by sending them a link. To do this, the meeting host should schedule the meeting either through the Zoom desktop app or web portal, and send the invitation via email or by copying the link and sharing it via text message. From here, the recipient can click to join the meeting via in the link in the invite, which will then prompt them to install the Zoom app. Once the user clicks to download , a file called Zoom.pkg will appear at the top of their Downloads folder, or in the bottom downloads panel on their Chrome browser or the top right corner of their Safari browser. Clicking this will launch Installer and an Install Zoom window. After clicking through the prompts to Install, they will have Zoom on their computer. Step one complete! For this step with my own grandparents, I had my grandma point the phone at each prompt and told her exactly what button to click on throughout the installation process.
