Installation failed when installing Code Composer Studio

Hi,
I was having trouble in installing Code Composer Studio in one of the PCs in the office. I waited for a several hours and then tried to reinstall but I got the same error message. I checked the server as recommended by the message and it seemed correct.
Anyway, please help me resolve the error. The software is needed ASAP. Thanks in advance.
