Resolution

  1. Make sure to use the Right click on setup.exe and choose "Run As Administrator"
      
  2. Extract the installation to local hard drive C:
      
  3. Disable Windows firewall temporarily or open ports in the range 4520-4539 bi-directionally on the firewall. 
      
    For example Windows 7 firewall settings can be changed using following steps:
       
    1. Click on Start->Administrative Tools.
    2. Open Windows Firewall Settings.

      If there is any third party firewall enabled on the local machine then it needs to be disabled temporarily or the above mentioned ports should be opened on the firewall with the help of an administrator
    3. Note,  Remote Desktop Services (TermService) also could block the ports. The RDC needs to be disabled temporarily as well.
        
  4. Disable the port forwarding on the environment
