Keeps updating same version every time I sign on

Every time I open Zoom after shutting down my PC, I have to update the software. Its the same every time. It takes me back to 5 something and updates me to 6 something. I have logged onto the automatic update section of device management / Zoom web portal but both auto settings are switched off already. I also tried to make zoom an exception on my anti-virus but no joy. Its been happening for months, possibly a year and means I have to wait for a re-load every time I want to use the app. Any suggestions please? Thanks in advance 🙂 ( I have windows 360/5 ? not tech savvy I am afraid!)
