Hello,

I have issue to upgrade the affected version 5.0.11 to 5.0.12 on windows server 2008, when I install the msi rollback to the last version. Is anyone has the same issue.

thanks

Hi @elfayafi ,

Good day! Thank you for writing to live community!

Are you trying to perform offline install of the agent on top of Cortex XDR agent 5.0.11 installed on the endpoint? If that is the case, I recommend performing the agent upgrade from the Cortex XDR server. If you still want to perform the agent upgrade offline, you will have to disable anti-tamper protection using cytool commands and then you should be able to install the agent on top of the existing agent installation.

Hope this helps! Please mark the response "Accept as Solution" if it helps.

Regards,

thanks for your response, i tried to disable the anti-tamper protection but isn't the problem. I fixed the the problem by disable driver signature enforcement

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
