    Cortex® XDR™ Agents Deployed in Advertise Mode

    Depending on your Cortex® XDR™ agent release, you can install or upgrade the agent in Advertise mode.
    Advertise mode is an
    msi
     property you can set manually through the
    msi
     execution command line or through a deployment profile in a third-party deployment tool such as Microsoft System Center Configuration Manager (SCCM), allowing the Windows Installer to advertise the availability of an application to users or other applications without actually installing the application. For more information on advertise mode, refer to the Microsoft Windows official documentation.
    When you want to install or upgrade a Cortex XDR agent on an endpoint where a Cortex XDR agent release prior to 7.0.3 was installed in Advertise mode, whether the agent is still running or was removed from the endpoint, you must first clean the endpoint from the remains of the previous installation in Advertise mode. Otherwise, if you don’t clean the endpoint, the installation/upgrade of the Cortex XDR agent will fail.
    The following table summarizes the different scenarios of upgrade paths and the recommended workaround according to the different Cortex XDR agent releases:
    Upgrade to Agent Release 5.0.0 or Later
    Upgrade to Agent Release 7.0.3 or Later
    Upgrade to Agent Release 7.1.1 or Later
    Agent release 5.0.0 or later that was installed in Advertise mode
    Not supported, leads to undefined behavior.
    Contact Palo Alto Networks Support for assistance before you can re-install the agent.
    Not supported, you will receive an error in the agent installation log.
    Contact Palo Alto Networks Support for assistance before you can re-install the agent.
    You will receive an error in the agent installation log.
    Add the
    CLEAN_AGGRESIVLY=1
    msi
     property to you command line and proceed to install the agent.
    Agent release 7.0.3 or later that was installed in Advertise mode

    Palo Alto Networks recommends that you always upgrade to the latest agent release of the latest major version and use the
    CLEAN_AGGRESIVLY=1
    msi
     property to mitigate any Advertised mode related issues.
