Unable to install .net 4.8 runtime

Question

Updates always fail on my 2016 server standard vm. When attempting to install .net 4.8 runtime i received the error the component store has been corrupted. I have attempted DISM /ONLINE /CLEANUP-IMAGE /RESTOREHEALTH and received the error The source files could not be found.

I have since tried using other sources including the original iso used to install the os in the virtual DVD drive using DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:wim:D:sourcesinstall.wim:2 /LimitAccess which returned this "The source files could not be found. Use the "Source" option to specify the location of the files that are required to restore

ion on specifying a source location, see [http://go.microsoft.com/fwlink/?LinkId=243077].``"

Also tried using another server in the domain by sharing the windows drive and using this command Dism /Online /Cleanup-Image /RestoreHealth /Source:\\SERVER03\Windows /limitaccess and received the same error as previous attempt.

Additionally tried sfc /scannow and received this error "Windows Resource Protection found corrupt files but was unable to fix some

of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For

example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not

supported in offline servicing scenarios." after doing the above DISM attempts.

Any help would be greatly appreciated as it is a production server and one of the software items on it has a deadline coming soon for this to be installed.

Hi @Randy DeMasters ,Welcome to Microsoft Q&A,

1. Download via the official website: Visit Microsoft's official websitehttps://dotnet.microsoft.com/en-us/download/dotnet-framework/thank-you/net48-web-installer: On that page, you should be able to find a download link for the .NET Framework 4.8 runtime. Click the download button and follow the prompts to download the installer. Run the installer and follow the prompts to complete the installation.
2. Because you say you're a production environment. If you have Visual Studio installed.

You can install the target SDK in modify.

Best Regards,
