Hi @Chris Dabek
Please try downloading and installing the client directly from: https://www.microsoft.com/en-us/microsoft-teams/download-app
Please make sure you meet the system requirements to download Teams:
Please try turning off the firewall during installation.
If the above does not work please try disabling the anti-virus/spam program through the service:
Run: services.msc as an admin, stop all A/V services, run the installer for Teams, then once done, re-enable the A/V services.
