Hi all,
We have a Windows 2016 server environment which runs fine.
I am installing Office 2019 on several servers. Which also work fine. However after a short while all Office applications stop working and give the Oops something went wrong.
When I check the event viewer, every time I start any office app the following entry appears in the event viewer.
Activation of app Microsoft.Windows.Cortana_cw5n1h2txyewy!CortanaUI failed with error: This app can't be activated by the Built-in Administrator. See the Microsoft-Windows-TWinUI/Operational log for additional information.
When checking the other logs:
The app Microsoft.Windows.Cortana_cw5n1h2txyewy!CortanaUI could not be activated for the Windows.BackgroundTasks contract because the current user is an Administrator with a full token. Only split token Administrators can activate apps.
Things I have tried
repair, which works for a very short while
Created new Office 2019 installation media
Tried different servers
Tried to install it as a local admin
user account control approval mode for the built-in administrator
