Fix a Microsoft Installer Conflict

On Windows endpoints, if you
Enforce GlobalProtect for Network Access
in a GlobalProtect portal agent configuration and then you upgrade from an older version of GlobalProtect Agent, the installation can fail and the enforcement configuration continues to block all traffic.
This issue is caused by an OS limitation. It occurs when multiple Microsoft installer (
)instances are running at the same time on the Windows endpoint. Use the following procedure to correct the installer conflict.
  1. Restart the endpoint.
    Use the
    command to reboot your Windows endpoint.
  2. Stop all third party installers that are running in the background.
    1. Press
      Start the Task Manager.
    2. In the Task Manager, find any third-party
      programs that are currently running (for example,
      msiexec command line - Google Search
    3. Select the third party installer and click
      End Task
      to stop it.
  3. Restore the existing version of GlobalProtect, then upgrade.
    1. If necessary, install the older, existing version of GlobalProtect to repair it. This step is necessary if the upgrade continues to fail.
    2. Allow the upgrade to proceed as expected.
