Several Draycir products are supplied with so-called "chained installers", so that launching one installer will automatically launch a subsidiary installer. This simplifies the installation process. For example, the Credit Hound Express installer bundles together the installer for Credit Hound Express and the installer for Spindle Professional for Credit Hound Express, and the Spindle Professional installer contains the installers for Spindle Professional and also the Safenet client.

In Windows Server 2008 and later, these chained installers can cause the Windows Installer Coordinator to display 'Preparing for the first use', with the progress bar cycling indefinitely.

Technical Explanation

This problem is caused by an incompatibility with the Embedded MSI technology and the Windows Installer Coordinator. The Coordinator is responsible for keeping multiple MSI installations from running concurrently.


Microsoft have written a KBA regarding this issue. The work around for this issue is to disable the Remote Desktop Session Host Windows Installer for the duration of the installation. For information on how to disable the RDSH temporarily, click on the following link.

The MS document advises modifying HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Terminal Services\TSAppSrv\TSMSI\Enable

If this cannot be found then you may need to update the key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\TSAppSrv\TSMSI\Enable
