Outlook Plugin

My laptop computer has tried to download Outlook plugin 5.17.0.978.0 unsuccessfully. 

How do I get my computer to remove the attempt or to install it successfully?

I did get their "How to access the meeting schedule email template. it did direct me to start with signing with Zoom web portal, which I did. Than to find the navigation menu and click Advanced than Branding. I didn't see any navigation menu to click Advanced. 

Can anybody help me with this unsuccessful attempt?
