KimaiDotNet based Office Add-ins

Bringing Kimai into the tools you spend your time in

Published on Saturday, May 29, 2021

As of v1.0.0.0 released on 09/03/2023 the VSTO is signed with an open source code signing cert from Certum this should mean the installation is automatically trusted.

If you installed a version before v1.0.0.0 you must uninstall it before installing v1.0.0.0 as the change in signing cert will prevent the upgrade working.

Until I get a real certificate you will need to install this self-signed certificate as a trusted root certification authority to be able to install the add-in.
