Issues with upgrades

Hello, The past couple times I have used Zoom I have had issues with upgrades---meaning I am signing in to my meeting and then there is a box that pops up  asking. me to do the upgrade. So I click to do the upgrade, and it looks like it is going to do the upgrade  but then I get a message the upgrade failed. Last time I tried to use zoom because  I was unable to do the upgrade, I could not attend my meeting. Any thoughts or help with this would be appreciated.
