Upgrade agent failed

L0 Member

I have encountered the following issue of failed agent upgrade on a Windows laptop, showing the following message:


XDR Agent failed to upgrade from version to version on LAPTOP-xxxxxxx with error: Windows Installer DB: Current agent registration is missing.


Anyone has experienced this as well? How can I solve the issue and upgrade the agent?

Hello @T.Lee056969 


There could be the reason that  Distribution ID is missing from installation package.


The easiest way to see if Cortex XDR is registered, is to look at the "InstallerMachine.reg" file inside the agent tech support file and search for "Cortex XDR".


The only workaround solution for the affected machine is running the Cortex XDR Cleaner tool to remove the old agent and reinstall the Cortex XDR agent.


Please note that this is an assumption and basic troubleshooting which you can try. Please feel free to open TAC support case to get the RCA.
