Best Practice Examples

Example 1 Basic ClickOnce Installation

User A installs the ClickOnce Add-In in May-17. Then when we release the June-17 Add-In, User A does not have to do anything because Excel automatically installs the latest Add-In. This option is recommended for all users.

Example 2 Basic InstallShield MSI Installation

User B installs the InstallShield MSI Add-In in May-17. Then when we release the June-17 Add-In, User B has to uninstall the May-17 Add-In with Control Panel and then install the June-17 Add-In.

Example 3 Switch from InstallShield MSI to ClickOnce Installation

User C already has the SpotlightXL Add-In installed from previous months, but wants to automate the Add-In installation going forward. User C has to uninstall their Add-In using Control Panel, and then install the May-17 ClickOnce Add-In.

Example 4 Switch from ClickOnce to InstallShield MSI Installation

User D installs the ClickOnce Add-In in May-17 and gets the latest Add-In in June-17 automatically. If the user does not want to get the latest Add-In automatically in July-17, then User D can uninstall ClickOnce, uninstall the current Add-In, and then install the June-17 InstallShield MSI Add-In so that the process will be manual going forward.
