Cortex XDR Installation issue for Windows 7 SP1 and Windows 2008 R2 SP1

[D.Sanghvi]

Hi Community,

I’m facing an issue while trying to install Cortex XDR Agent (7.9-CE) on Windows 7 SP1 and Windows 2008 R2 SP1 systems. According to the compatibility documentation, these platforms are supported, but I’m encountering the following error during installation:

"Cortex XDR requires Azure Code Signing support. See Microsoft KB5022661 for details."

In my lab, I ran into the same issue on a Windows 10 system, which was resolved after updating the OS. However, for Windows 7 and 2008, I’m unsure about the exact KB patch that needs to be installed to fix this.

Versions I tried on CE Sytems:

1. 7.9.100.30126 [CE]
2. 7.9.103.53496 [CE]
3. 7.9.101.42637 [CE]

Has anyone else encountered this issue, or could you guide me on which patch is required for these operating systems?

Any help would be greatly appreciated.

Thanks in advance!

You need to use NO_ACS_SUPPORT=1 flag as parameter to MSI installer.

Hi,
I’m facing the same issue and need to find the correct KB to manually install.

Refer to this link: KB5022661 - Windows support for the Trusted Signing (formerly Azure Code Signing) program.

Please note that the KB might be replaced by a more recent one, so it’s important to track the KB history.

Hi @D.Sanghvi, thanks for reaching us using the Live Community.

As @maximk states, you need to use that parameter in the msi installation, you don't need to install that KB with the agent version 7.9.103 CE. It's in our documentation under the section "Install Cortex XDR agent on unsupported-ACS OS versions".

Example: msiexec.exe /i AgentInstallerPackage.msi NO_ACS_SUPPORT=1
