Unable to install PSB Computer Protection or Server Protection due to .NET Framework 4.7.2 dependenc

This discussion has a more recent version.


  • Unable to install PSB Computer or Server Protection due to .NET Framework 4.7.2 dependency. This affects multiple operating-systems, including Windows 7, 8 and Windows 10 and Windows Server.
  • This can trigger the error: NET Framework of version 4.7.2 or greater is not installed - msi error 1603 during installation.


During the channel upgrade, the client requires .NET Framework 4.7.2 and installs it automatically if it is missing. This does not apply for the offline-installer, which assumes the depending .NET packages are installed.

In the event that .NET Framework fails to install, does not automatically install or requires manual installation, proceed with the manual installation of .NET Framework. It is highly recommended to ensure Windows Updates are fully updated to ensure successful installation of .NET Framework 4.7.2. Some Windows updates include the .NET Framework 4.7.2 update (example: KB4054530, KB4054542 etc.)

Note: Windows 10 versions before Windows 10 Anniversary Update (version 1607) do not support .NET Framework 4.7.2.
