5. Installation Best Practices

Even with the offline installer, installation can fail if the system is not prepared.

  1. Prerequisite Services: The Windows Update service must be active and the Windows Modules Installer service must not be disabled.
  2. Command-Line Deployment: For automated environments, the following command is standard: ndp48-x86-x64-allos-enu.exe /q /norestart
  3. Clean Boot: If installation fails, performing a "Clean Boot" of Windows (disabling non-Microsoft services) often resolves conflicts with antivirus software or background processes that lock system files.
