Answer 1

Hi @Michael Collins

The new Teams executable is stored within a hidden folder under your user profile. Press the Windows Key + R to open the Run dialog. Type in: %USERPROFILE%\AppData\Local\Microsoft\WindowsApps\ms-teams.exe
You can also search for ms-teams.exe in the C: drive to find the Teams executable file to open.

I understand how to try and re-install Teams, However I am unable to do so. My original post above contains the install log which shows the install failing. I havr attached the errro message I get when trying to re-install Teams. Thank You.
