How to deal with “Uninstallation failed” messages when trying to upgrade to the latest version of the Advanced Admin Console AddIn

April 29th, 2010

Yesterday I released version 0.5.2 of the Advanced Admin Console AddIn for Windows Home Server. As always I noted that you should UNINSTALL any previous version before installing the latest release. If you tried to install the latest version over an existing installation of AAC, you may find yourself now in a situation where you can’t uninstall the previous version (getting “Uninstallation failed” messages from the console) and also can’t install the new release (getting “Please uninstall previous version first” messages from the installer).

Please follow these steps to fix this issue:

  • Establish a Remote Desktop Connection (RDP) to your server (if you don’t know how to do that, please see this short How-To).
  • On your server, go to control panel –> Add/Remove programs. Find the entry for the “Advanced Admin Console AddIn” and click “Remove” to uninstall it. If you are prompted to reboot your server, really REBOOT YOUR SERVER before installing AAC again.

You can now install the latest AAC version from the console.

It’s very likely that now both (old and new) versions of AAC are now listed as installed in the settings dialog:


In order to clean up this mess you can use ASoft’s Addin Cleanup Tool. Download it and read the instruction from the Readme.txt (contained in the downloaded .zip file) carefully. You can use this tool to delete the orphaned addin entry for your previously installed AAC version (0.5.0 in this example).

    I followed the install procedure and the instructions in ASoft’s readme. His program starts running then dies in a few seconds. Nothing ever appears on the screen. From some other posts asking questions, it appears ASof is not responding to questions. Is there another application that does this, or can you provide instructions to edit this out of the registry?

    Are you sure that you unpacked the .exe file from the downloaded ZIP archive to the %PROGRAMFILES%\Windows Home Server directory? At first I had it silently crash on me, too, but when I put it in the aforementioned folder it worked just fine.

    I found the instructions for cleaning-up after the “I tried to install over an already installed add-in” problems at


    The link includes instructions for manually removing the duplicate entry from the installed Add-Ins tab.

    @Andreas M.
    Andreas — Thanks. I had it in the wrong directory. After moving it, it worked fine. I also created a shortcut on the desktop in case I need to run it again.
