ISSUE:

When installing Backup Exec 16 and OST Plugin install fails with "There is not a valid backup exec"

Another related error:

Symantec Backup Exec or NetBackup must be installed to continue setup

CAUSE:

The current OST Plugin does not recognize the Backup Exec 16 service so it does not think Backup Exec is installed.

RESOLUTION:

You must use the most recent version of the OST Plugin for Backup Exec 16:

DellOSTPlugin32-4.0.x

DellOSTPlugin64-4.0.x

Additional requirement:  The DR software version must be 4.0
