Installation fails on SQL Change Scripts step / MCCConnectionString registry key missing

PROBLEM

When installing MiCC Version 7.1.3.1, the Configuration Wizard stops at SQL Change Scripts.  The HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\prairieFyre Software Inc\CCM\Enterprise\MCCConnectionString registry entry is not present.

NOTE: Other errors can occur as a result of this registry key being absent, including errors in the MassTransitRuntimeService, or CCMWa.  This can also cause issues with IVR callbacks.

SYMPTOMS

• You are using Remote SQL
• You are not licensed for Multimedia Contact Center

The error produced by the cumulative update installer will look like the following:
