Workaround: error installing IIS Media Services on Windows Server 2016

tl;dr: Installing IIS Media Services 4.1 on Windows Server fails with error message "IIS Version 7.0 or greater is required to install IIS Media Services 4.1". Change the version information of the IIS in the registry, install the Media Services 4.1 again, and after successful installation change the registry key back.

Last month I had a PoC (prove of concept) with a customer and we needed to install the IIS Media Services 4.1 on Windows Server 2016. Unfortunately the installation failed with the strange error message "IIS Version 7.0 or greater is required to install IIS Media Services 4.1".


I did know this type of errors from my days where I did a lot of workshops regarding application compatibility of Windows applications migrating from Windows XP and Windows Vista to Windows 7 years ago in 2008. It's likely the issue where software checks only the first character of a version string.



We got the hint what to do in this forum post "IIS Media Service 4.1 failed to install on Windows10 because it can't recognize it is IIS7 or above" to change the version information in the Windows registry. That was really easy.

  1. Start the registry editor (regedit).
  2. Navigate to the path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp".
  3. Change the value of MajorVersion to 9.
  4. Install the Media Services.
  5. Change the value back to 10 (decimal; A in hex).

Detailed steps

Look for the value MajorVersion which is set to 10 in Windows Server 2016.


Change the value of MajorVersion to 9 just for the installation of the Media Services. Do not forget to set it back after the installation.


So the workaround did work on Windows Server 2016.


By the way, we got the latest version 4.1 of the Media Services from Microsoft Download, quite old from year 2012:
