Just to alert you to a problem I encountered when uninstalling this app prior to an upgrade.

When the Windows Home Server console install or uninstalls an add-in, it looks for the installers exit code to determine if it was uninstalled or not, but in some situations, an installer may have installed or uninstall, but sends a different exit code than what the console expects, such as in situations where files are locked and requires a reboot or similar. This causes the console to be confused, and therefore list add-ins as installed, even though they are not.
