After downloading the 3g file. I cant seem to find the correct executable to install the program on my 2003 Server.

There seems to be alot of "Symantec Backup Exec for Windows Server" installed packages, but none of these seem to work. I also tried all the setup.exe's that I could find. I really want to start testing this program, but I need to get it installed first. Can someone point me in the right direction?

Thank you
