I just had a bit of a scare with a misbehaving Windows Home Server add-in where the upgrade process went frightfully wrong. As such, I ended up with:

• The .msi for the add-in in the \\server\Software\Add-Ins folder.
• The list of add-ins saying the add-in was installed.
• No add-in actually installed.

Thank goodness there’s a great article over on HomeServerLand that tells you how to manually uninstall an add-in. I followed that process and the crisis was averted.
