error 0x800F081F while installing .net 3.5 issue Win 10 x64

Hello Steebo,

Thank you for posting your concern in Microsoft Community and we regret for the inconvenience. Let me assist you.

Please follow the below suggested methods and check if it helps to resolve the issue.

Sometimes, during an app installation, it needs a specific version of .NET Framework. In those cases, it might automatically install and activate that version. Is it the same in your case?

Also, are you trying to download and install .net framework because it is a pre-requisite for another application/program to run?

Now, 0x800F081F is one of the Windows update error codes users usually face. I suggest you to follow these steps to run the Windows inbuilt troubleshooter and check if it helps to identify any potential issue.

• Write Troubleshooting in the search box and hit enter.

• Click on Troubleshooting tab.
  

• Click on view all option on the upper left corner.
  

• Select the Windows Update option from the list.
  

• Click Next to run theTroubleshooter.

Write to us with the updated status and the required information for us to be able to assist you further.

Thank you.
