You'd do it like this to install the full version:
1. Install your CD into the CD-ROM, and double-click Browser.exe
2. Choose your setup language, and click OK.
3. Choose Start the Backup Exec Installation.
4. It will give you a welcome message, and you can click Next.
5. Choose the option for Local Install, and make sure Additional Options is selected. Click Next
6. The next screen is your license screen. Put in a license, hit Add, and do this for any additional licenses before clicking Next again.
7. The next screen shows all your options installed (with a tick next to the entry), or available as trials (with an empty white block). Click Next, or select what else you'd like to check out before clicking Next.
8. Review, and then click Install and let the installation run.
Once done, it will ask you for a username/password. You need to use a domain account (if you're in a domain) with admin rights. Backup Exec would be installed, and you can now start playing around with it.
Installing the Remote Agent can be done in 1 of 2 ways:
1. From Backup Exec itself (in your backup selection list, you would either browse your domain, or your selection list. Right-click the server, and choose: Install Remote Agent/Advanced Open File Option... and then follow the prompts.
2. From the installation directory itself, choose Browser.exe, and when the splash screen shows up, choose: Start the Backup Exec Remote Agent Installation. Follow the prompts.
