Hello,
As per the following technote regarding 5520 SP 1, check if the files versions have changed as described in the technote:
http://support.veritas.com/docs/278701
Try the following steps:
1. Verify permissions to the directory specified in the error message, restart the backup exec services and confirm if the BEDB_log.ldf is present now
2. If the file is not present then extract the BEDB_log.ldf from the data.cab file located in the installation media ( \winnt\install\BE\data.cab ) to C:\Program Files\VERITAS\Backup Exec\NT\Data
3. Reboot the server as per previous failed installation which requires a reboot
4. Restart installation process
If the issue persists, revert with details.
