No idea why this happens. But it’s probably part of the crappy pushiness of Zoom to get people to install their app that makes them trigger a download of the installer because either they are not detecting that Zoom is already installed at the right time, or they are so eager to download the installer that they don’t even care about whether or not you already have it installed.
I’ve disliked Zoom since the beginning for their antics, and the only reason I have it installed is because I have to for the meetings at work, and the work computer belongs to the company I work for anyway, not to me.
I would never install Zoom on my own computer.
Click on the meeting, where you will land on a download landpage. Then click the big download blue button in the center of the screen. WHen you click it a link will appear in the 2nd row below the blue button, something like "continue from browser", click on that, and you are golden
Its always great to see the reactions that gathers. Its a true rainbow: bemusement, curiosity, exasperation, outright suspicion...and everything in between!
