McAfee Application and Change Control (MACC) 8.x.x, 7.x.x, 6.2.x, 6.1.x
Microsoft System Center Configuration Manager (SCCM) server


You have an SCCM server that is set up to deploy and install packages on a 32-bit or 64-bit Microsoft Windows operating system endpoint. The SCCM server communicates to the SCCM client, which is responsible for deploying the package and installing the application on the Windows endpoint. The SCCM client itself is pushed and installed by the SCCM server.

With Application Control enabled, the SCCM client installation, reinstallation, or upgrade might fail. You might observe write-denied and pkg-modification-prevented events.


To resolve the problem, a two-step configuration is needed.
  1. Add the SCCM client installation user as a Trusted User.
    Determine which account is the Client Push Installation user (SCCM client installation user) on the SCCM server:
    1. From the Configuration Manager console, click Administration, expand Site Configuration, and click Sites.
    2. In the top ribbon, select Client Push Installation from the Client Installation Settings drop-down list. The Client Push Installation Properties dialog box displays.
    3. Click the Accounts tab. The SCCM client installation user displays in the Client Push Installation accounts section.
      NOTE: The account must have local administrator rights on every computer on which you want to install the SCCM client.
  2. Add Wakeprxy.msi as an Updater.
NOTE: Make sure that you have the default MAC rules for SCCM and SMS applied.
