Installation stops

Hi

I tried to update Teamviewer to the newest version 14.1. 9025, but this did not workout very well. On all three computers the update failed and distroyed the existing installation. Installing the newest version stopped with the last step: installing the teamviewer_server (see screenshot).

The only way out is killing it with the taskmanager. TeamViewer does work, but is completly dissapeared after restarting Windows.

Reinstalling an older version did work.
