Windows 10: Windows 10 version 1903 or 1909 won't install

I'm always met with the error code 0xC1900101 or 0x8007042c. It usually goes through the whole update process but when I go to check if it's updated it either says my version of Windows has reached the end of service or there were some problems installing updates.

Version 1909 stuck without 1903 installed

Hi gabe

The standard download for version 1909 is only 300MB if you have version 1903 already installed, if you did not have version 1903 installed, that download should have been much bigger and included everything it needed to install, because 1903 is not pre-requisite
for version 1909 . . .

Try re-starting your PC maybe 3 times in a row to see if that prompts 1909 to begin the installation phase . . .

 

Version 1909 stuck without 1903 installed

I started installing version 1909 which was only notified today, Nov. 24th, without realizing version 1903 failed to install on Sep. 29th when it was received --error code 0x80070643-- so the most recent version I have is 1809 as of May 5th and 1909 is
stuck at 100% downloading. How do I stop it so I can manually install 1903?

 

Completely missing Dot Net in Windows 10 -1909?

.NET Framework is built-into Windows 10 version 1903 and Windows 10 version 1909. It is not possible for at least this version of the .NET Framework to be installed.

The error you have received, is likely due to the fact the application you are attempting to use, is specifically trying to target a version of the .NET Framework you don't have installed. I suggest using official Microsoft tool to download a Windows 10 version 1909 ISO. You can use the Media Creation Tool and/or the Upgrade Assistant. Windows ISO Downloader was only recently updated to support .NET Framework 4.8 on November 8th 2019. If you were not using Version 8.22, and would like to still use the tool, you need to download that version.

RaymondCC .NET Detector looks at registry keys that are created when you install .NET Framework. It does not support the .NET Framework version that are included with Windows 8.0+

The built-in version of the .NET Framework for Windows 10 version 1903 was .NET Framework 4.8

.NET Framework 4.5+ has never been located in the list of Windows Features for any version of Windows. The lack of .NET Framework 3.5 is likely due to your WinSxS directory not containing it.

You can install .NET Framework 3.5 if you run the same command you ran, but provide a source, to the components you need.

This is due to the fact the .Net Framework 4.8 is already installed on Windows 10 version 1903 and Windows 10 version 1909. .NET Framework 4.8 is an in-place upgrade to .NET Framework 4.5

This normally only happens when you have moved vital folders like the user's profile to a non-standard location.

Your inability to install .NET Framework 3.5 is extremely easy to fix and likely the reason your unable to run the third-party application. Perform the following steps to solve that problem.

1. Download a Windows 10 version 1909 ISO
   
2. Mount the ISO within Windows 10
   
3. Run the following command, the command assumes, the drive letter assigned to the virtual mount is D:
   
   • DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
