installation tutorial for symantec mail security 6.5 for MS Ex 07

Please, Where can i have a installation tutorial for symantec mail security 6.5 for MS Ex 07 ?

The documentation that I had after buying this product speaks to launch the insatallation from the CD, however my dealer confirmed to me that there is no cd to be provided with the purchase of license symantec and there is just FileConnect symantec to download softwares.
The problem is that the FileConnect contains no CD/DVD image for Mail security as explained in the documentation.

Thank you
