Start by running the PowerShell command from the issue and inspect the installer invoked from scripts/install/install.ps1, along with the generated package contents. Reproduce the missing-file error during the oci_cli installation and trace why that Windows path is not available. Done means the installer completes successfully on Windows 11 and the CLI is usable.
