McAfee Endpoint Security (ENS) Common platform module 10.5.x, 10.2.x


Installation of the ENS Common platform module fails with the following error messages generated in the log files.

NOTE: The error message described contains a typographic error, but it is reproduced to show how the message actually appears in the product.

Example error messages in McAfee_Common_Bootstrapper_XXXXXXXX.log:

NiAMH.dll or Nia64.dll library validation fails even if it is signed with a valid certificate.


The mentioned dlls are signed in an unusual and possibly outdated manner. The signing method for the dlls does not comply with RFC 5280 (see https://www.ietf.org/rfc/rfc5280.txt) in the PKIX Certificate and CRL Profile that is required for ENS 10.5.x and 10.2.x to be able to validate the certificate.


This issue is resolved in Endpoint Security 10.5.2, which is available from the Product Downloads site at: http://mcafee.com/us/downloads/downloads.aspx.

NOTE: You need a valid Grant Number for access. KB56057 provides additional information about the Product Downloads site, and alternate locations for some products.

Updates are cumulative; Technical Support recommends that you install the latest one.
