Windows downloads Zero Tier, but will not install

I downloaded Zero Tier on my home computer. It will be used to remotely communicate with a mini pc that I will deliver to a site. So while still here at home, I hooked up the mini to my monitor, and connected a mouse and keyboard. I went to the ZT site and downloaded the software for Windows (mini has Windows 11). The software downloaded and says it has all the data to install. But installation did not occur. I tried Run as Admin and Repair, no good. What can be wrong? I’m not an IT guy.
