Seems like you missed to upload all 4.5 files to your server.

When upgrading your 4.1.6 Vivvo website, just make sure to carefully read Readme.txt file that comes with the Upgrade script and there should be no troubles upgrading to v4.5. But if needed, feel free to contact the support staff (https://www.vivvo.net/support/contact).

Also, be sure to keep a valid backup of your files/database.
