in a GlobalProtect portal agent configuration,
and then you upgrade a Windows endpoint to a newer version of the
GlobalProtect app, installation can fail and the enforcement configuration
can block all traffic.
This issue is caused by an OS limitation
that occurs when multiple Microsoft installer (
msiexec.exe
)
instances run simultaneously on a Windows endpoint. You must use
the following procedure to resolve the Microsoft installer conflict:
Restart the endpoint.
Stop all third-party installers that are running in the
background.
Press
Ctrl+Alt+Delete
,
and then click
Task Manager.
In the
Task Manager
, locate all third-party
msiexec
programs
that are currently running (for example,
msiexec command line - Google Search
).
Select the third party installer, and then click
End
Task
to stop the installer.
Restore the existing version of GlobalProtect, and then
upgrade to the newer version of the app.
(
Optional
) If necessary, re-install
the existing (older) version of GlobalProtect to repair it. This
step is required if the upgrade continues to fail.
