4. This will bring up Windows Features, from here, check the box next to Microsoft .NET Framework 3.5 and click on OK.

Note: If the checkbox is already checked, then you will need to repeat the process, first to uncheck it, and then to check it again. To complete the reinstallation process.

Enable Group Policy to Fix Error Code 0x800F081F

Another method that you can use to fix error code 0x800F081F is to access the group policy editor and enable the appropriate policy within it. Group policies have an overarching impact on the functionality of the operating system, so it’s very possible that this could rectify your problem.

Enable .NET Framework via DISM Command

This method entails using the DISM command to enable the .NET Framework component.

However, before you can use this method, you will need a copy of your operating system in ISO form. If it’s Windows 10, then you should be able to acquire it using Microsoft’s Media Creation Tool.

Note: You can find it on Microsoft’s official website.

For older versions of Windows, you’ll need to use your Windows CD or the Windows Image file you were given, when you purchased the operating system.

Once you have your operating system in ISO form, only then are you ready to proceed.

The first thing you’ll need to do, is mount your ISO image to a virtual drive. This is a fairly simple, seamless process, which you can do, providing you have the appropriate software installed on your system. The two tools that I recommend are:

• PowerISO
• Daemon Tools

So, go ahead and download one of these tools, and familiarise yourself with it.

1. Once you’ve mounted the ISO to a Virtual Drive, press + R, type cmd and click on OK.

2. Once Command Prompt loads up, type the following command, followed by Enter:

dism /online /enable-feature /featurename:NetFx3 /All /Source:[Drive]:\sources\sxs /LimitAccess

Note: Replace [Drive] with the letter of the virtual drive that you’re using for your Windows ISO image file.
