How to: Install a ClickOnce Office Solution
End users can install document-level customizations and application-level add-ins by doing the following:
Running the Setup program that is created when you publish your solution. For information about the Setup program, see Publishing Office Solutions by Using ClickOnce.
Opening the deployment manifest file, which ends with the extension .vsto.
Opening a customized document or workbook, if the prerequisites are already installed and the security policy is set up to grant trust to the solution.
End users can uninstall an Office solution the same way that they uninstall other applications on the computer.
