The error occurs during the Configuring Windows features process. The installation ends prematurely.
The Starry Night installer is trying to turn on a Windows feature called .NET Framework 3.5.1.
Please follow this guide to enable it yourself,
Windows 7: http://www.techhit.com/how-to/install-.net-3.5.1/windows7/
Windows 8/10: https://docs.microsoft.com/en-us/dotnet/framework/install/dotnet-35-windows-10
Please try the Starry Night installation again once .NET is enabled.
Thank You very much, I could install the Software. BR Norbert
