Symantec Backup Exec 2012 and Windows Agent

I have a Symantec Backup Exec install which I am using to backup VMs (using windows agent) to a DELL DR4000 D2D appliance. Windows agents install fine on VMs and/or physical machines and backups go fine.

There is however something that I dont understand. The agent that installs on any system has an odbc connection that gives an error (when I click on configure) about missing a becatdrv.dll.

Is this a problem I have to correct? Why is it happening? This is only on the clients I am backing up. The server has the ODBC and it works and apparently the becatdrv.dll is present
