Solution The CMM interface failed to start because dynamic port assignment was disabled on this server.  Instead to enable dynamic port assignment you can set a fixed port number, please follow steps to set a fixed port for CMM:  Edit file "cmmOptions.xml" and give a fixed port number, i.e "3115" similar as below: 

D:\Apps\Siemens\CMM\1926\Config\cmmOptions.xml
