Problems installing Cortex XDR to a user

L0 Member

Hello Palo Alto Team.


When installing Cortex XDR on a user, we must disable Windows Anti-Tampering, due to the following error:




If Windows Anti-Tampering is disabled, we still have installation problems.




Operating system name: Microsoft Windows 10 Pro


Operating system version: 10.0.19042 N/D Compilación 19042

I see that as well on a handful of assets as well. I spoke to the tac on this and they basically said to either un-install or run the cleaner.

you can also try to use cytool to disable

cytool protect disable process
cytool protect disable Registry
cytool protect disable file
cytool protect disable service


Having said that I always see this on a handful of assets, and find it is just quicker to either uninstall the old version then re-install.

would be nice to know why this is happening. 


I have tried uninstalling and running the cleaner. Also with the cytool tool to disable.
this is the error that appears when reinstalling the new version.

Hi @irissentinel


As @PeteJacobCF mentioned, you first need to disable the Agent Tampering protections. 


You need to open CMD in admin mode, cd to "c:\program files\Palo Alto Networks\Traps\", then type "cytool protect disable". You will need to enter the Supervisor/Uninstall password. All protections are disabled. Now you can continue with uninstall/install process.
