CMM installation help needed

Trying to install CMM 10.0.3 and immediately getting error:    Content Migration Manager Setup Wizard ended prematurely

Content Migration Manager Setup Wizard ended prematurely because of an error.  Your system has not been modified. To install this program at a later time, run Setup Wizard again. Click the finish button to exit the Setup Wizard.

Solution Customer had a 4-tier client on the system at one point and CMM was picking up on the TC_ROOT variable in the Teamcenter registry key. We deleted the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Siemens\Teamcenter

Now setup runs correctly.
