my windows 11 machine - pushed out the update and it disabled cortex and never installed 7.6.  I had to reboot to get Cortex 7.5.x to restart.  

Dear Shmuel,

Thank you for log. Noticed that you have "Installation success or error status: 1603." in your log. This is typical msi package installation error. 

That error might related with the permission of the installer account but i guess in your case, windows installer cannot able to install an app which is already existing on the system and checking XDR folders, still there and throwing this error.


Im gonna recommend to try installation manually first. check detailed installation logs. please use below command.

msiexec /i XDR_pkg_x64.msi /l*v c:\install.txt


and then please try uninstall manually and manually install again.

Dear Papuga


7.5 agent is not supported for Windows 11. I'm recommending to use 7.6 agent for Windows 11

Hi @Shmuel,


As @etugriceri mentioned, error 1603 could be related to permissions for the msi installed. I reason for this could be related to pending reboots in the machine. For instance, Windows updates were applied, and the endpoint needs a reboot to finish installation. MSI gets "blocked" and does not allow other msi installations. I would suggest a reboot if possible and try again.
