Install and Remove AAD Sync

Been doing some automation around AAD Sync lately and find it convenient to start from scratch without throwing away the whole machine.  In that case I just uninstall AAD Sync, then re-install.

In each case I’m just calling msiexec.exe with the command line options.  The only secret sauce is in the MSI parameters; dug those out of the MSI using Orca.

Here’s the script snippets:

Start-Process -FilePath msiexec.exe -Wait -ArgumentList @(


'/x "C:\InstallationFiles\AADSync\Synchronization Service.msi"'



Invoke-Sqlcmd -Query "DROP DATABASE ADSync" -Verbose


Start-Process -FilePath msiexec.exe -Wait -ArgumentList @(


'/i "C:\InstallationFiles\AADSync\Synchronization Service.msi"'

'/lv* C:\Temp\SynchronizationService.log'















UPDATE - March 2, 2014: had a conversation with an authoritative source about this approach and it turns out to be not very useful.  The AAD Sync wizard does a lot of work, and bypassing it has the potential to break a deployment when AAD Sync gets updated.  The DevOps nerd in me protests any wizard getting in the way of automating a system, but all is not lost since the wizard can be automated with an answer file.  More on that later.
