Hi Theodore,
To install AOFO, perform the following steps:
1. Launch Backup Exec for Windows Servers console (assuming you're using Windows)
2. Click TOOLS menu, then select 'SERIAL NUMBERS AND INSTALLATION'
3. Click NEXT
4. Accept the default of 'Additional Options', click NEXT
5. Enter the serial number of the AOFO that was given to you by Veritas, click NEXT then follow the steps from that point to finish installation.
6. Server will require a reboot.
Hope this helps
Kent
