When using Windows Remote Services (on Windows Server 2008 R2) with the Windows Installer Coordinator on, installation of BillQuick 20xx is unsuccessful. At the end of BillQuick 20xx InstallShield Wizard, the Windows Installer Coordinator does not close. It cycles until the user clicks Cancel.
This affects the BillQuick installation and its working.
The workaround for this issue is to disable the Remote Desktop Session Host Windows Installer for the duration of the un-installation. See the below information for more.
