McAfee Agent (MA) 5.6.1, 5.6.0

When you log on via Remote Desktop to a XenApp Citrix Server, you can sometimes get the following error message:

UpdaterUI.exe
The Application was unable to start correctly (0xc0000018). Click OK to close the application

UpdaterUI.exe failed to run on some systems, when the memory address needed by McAfee Agent (libeay32.dll), was used by other programs.

The issue documented in this article is resolved by McAfee Agent 5.6.2 and later, which is available from the Product Downloads site.

NOTE: You need a valid Grant Number for access. See KB56057 - How to download Enterprise product updates and documentation for more information about the Product Downloads site, and alternate locations for some products.

To view other known and resolved issues, see KB90993 - McAfee Agent 5.6.x Known Issues.

McAfee Agent 5.6.2 now loads the libeay.dll in a dynamic memory location.
