Upgrade : I cannot download the latest upgrade and cannot install the full product

Hello,

Yes, I would recommend uninstalling the Zoom Workplace App and then trying to install it again. You can find out more information here: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0065146

I hope this helps and please make sure to mark the solution as accepted if this information is what you needed.

Thank you,
