If you still cannot open the Zoom App, you can still join by the browser. Once you click on the Zoom Link, two things happen. One, a new tab is opened in your Chrome Browser and two, the Zoom App opens automatically.
To use the browser instead of the Zoom App, once the Zoom App opens up, close out of it. You will see there is a option in the new Chrome tab that opened up with a link that says "If you cannot download or run the application, join from your browser". Click this and you will join Zoom through the browser instead of the Zoom App.
