Windows Installer Coordiantor Hangs on Windows Remote Desktop Servers

Attempting to install an application on Windows Server acting as a RDS resulted in Windows Installer Coordinator hanging indefinitely with the message:
Please wait while the application is preparing for the first use
followed by the Windows Installer error message:
Install server not responding
This occurred on both Server 2012 R2 and Server 2019.

The workaround is the same for both versions and involves temporarily changing a local group policy setting:

  1. Open Local Group Policy Editor (gpedit.msc)
  2. Navigate to:
    Computer Configuration -> Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Application Compatibility
  3. Locate the setting: Turn off Windows Installer RDS Compatibility
  4. Change it to Enabled and click Apply

At this point you should be able to retry or restart the installation of the application. Once complete, revert the group policy setting back to the previous value (default is Not Configured).
