Resolution:
Check in the C:\Program Files\Documentum\CTS\config folder, and check if any of the XML files in this folder are empty, 0KB size. If so, take one of the backup files of this xml file (in the same folder with extension .bak.00) and rename it to the original xml files. This should allow you to continue with your installation
