Can't install TeamViewer - already installed on this computer...

Issue

TeamViewer v15 Host (.exe version) was installed on a PC that already had a TeamViewer v14 Host (.msi) version installed. The installation completed successfully, but it didn't remove TeamViewer v14 .msi Host from the programs list. Trying to uninstall TeamViewer from there, not only removed v14 entry, but also partially removed and completely broken v15... Trying to remove v15 was now failing with the following error:

Windows cannot find 'C:\Program Files (x86)\TeamViewer\uninstall.exe'. Make sure you typed the name correctly, and then try again.
