error 1603 during installation of Cortex XDR

L0 Member



i currently am trying to install Cortex XDR on a windows server 2019.
The Server itself is a basic 2019 installation with no special features.
I tried it with the command line (Started as Administrator) aswell as just running the MSI but nothing is working.

Ive tried a bunch of different things, including that Microsoft recommends for the Error 1603 but i cant get it to install.
Does anyone have any ideas?
i thank you all for your answers.

Hello @Jan_Schulz ,


Thanks for reaching out on LiveCommunity!


1603 is basically generic error for Microsoft. To troubleshoot this, we need to check the installation package, fetch some logs from the Server, confirm the network connectivity etc. It would be great if you open a TAC support case to resolve this.
