About the .NET Framework 4.7.1
The .NET Framework 4.7.1 is a highly compatible and in-place update to the .NET Framework 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, and 4.7. However, it can run side by side with the .NET Framework 3.5 Service Pack 1 (SP1) and earlier versions of the .NET Framework.
When you install this package, you can see that it’s installed as Update for Microsoft Windows (KB4033369) under the Installed Updates item in Control Panel.
The .NET Framework 4.7.1 is available on Windows Update and on Windows Server Update Service (WSUS). It will be offered as a recommended update on Windows Update.
Note A recommended update may be installed automatically on all supported platforms based on your computer settings on Windows Update.
I advise just remove this KB4033369 and restart your machine… this is recommended update but not mandatory. Hope this will fix your issue…
