Hi
quite some problem here:
had Teamviewer 12 installed, but got message, that my partners have version 13 and i should update.
Unfortunately, this installations fails. the error message says: installation failed ...then it crashes, i can't click on the "details" button.
i tried:
-running as administrator
-deinstallation of version 12
.... nothing helped and i don't have any teamviewer anymore on my pc 
would appreciate help
