Yesterday I ran across a program I tried to install on my terminal servers that just hung up with Windows installer Coordinator running.

I found that there is a setting in Group Policy that disables Windows Installer Coordinator and allows the install to finish.

open the group policy on the local machine

go to local computer policy/administrative Templates/Windows Components/remote desktop Services/remote desktop session host/application compatibility.

there you will find “turn off windows installer RDS compatibility” set it to enable.

you should now be able to complete the installation.

Once finished I set the parameter back to not configured.

Hope this helps
