Hi Neil, how did you perform the uninstall? Through the console or via Add or Remove programs in control panel? The later method is not supported and should only be used in case of emergency. Maybe try to download the latest version, copy it to the Add-Ins folder in the software share of your WHS, install the Add-In again in the console and in the next step try to uninstall again in the console. Best greetings from Germany Olaf
