Unable to install Data Loss Prevention (issue: failed to register DLL file error)

Technical Articles ID: KB75886
Last Modified: 12/21/2021

Environment

McAfee Data Loss Prevention (DLP) Endpoint - all supported versions
McAfee ePolicy Orchestrator (ePO) 5.x

For supported environments, see KB68147 - Supported platforms for Data Loss Prevention Endpoint.

Problem

DLP Endpoint installation fails. The DLPAgentInstall.log contains the following:

MSI (c) (F0:74) [11:04:40:857]: MainEngineThread is returning 1603
=== Verbose logging stopped: 7/3/2012 11:04:40 ===

The log also contains a message similar to the following:

MSI (s) (A4:BC) [11:04:39:639]: Product: McAfee DLP Agent -- Error 1904. Module C:\Program Files\McAfee\DLP\Agent\x86\fcplou.dll failed to register. HRESULT -2147024770. Contact your support personnel.

NOTE: The failure occurs if the Messaging API (MAPI) files are no longer installed on the computer.

Cause

If your computer has Microsoft Outlook or Outlook Express installed, the DLP Endpoint installation looks for the MAPI files on the operating system. When it can't find these files, it does not completely install.

Solution

Make sure that you have the proper MAPI files installed in the file structure on the system. Perform a search for MAPI32.dll. If the search does not yield results, the file is missing from the system.
