2. Run the .NET repair tool.
3. Run SFC scan.
4. Run DISM scan.

1] Enable .NET Framework in the Control Panel




Many apps or software require a specific version of the .NET Framework. Sometimes, users encounter a message while running an app or software, “This application requires .NET Framework to run, but that version is not installed on your system.”

You can enable the .NET Framework version in the Control Panel – even better – do it in Clean Boot State.

Type Windows Features in the Windows 10 search box and click “Turn Windows features on or off.” Now, select the required version checkbox and click OK.

This will install the .NET package on your system. You should be connected to the internet while enabling the .NET Framework using Windows Features. Reboot your device if you will get such a prompt message on the screen.

Do note that you need not select the checkboxes for Windows Communication Foundation (WCF) HTTP Activation and Windows Communication Foundation (WCF) Non-HTTP Activation, as these features are required by developers or service administrators.

2] Run .NET Framework Repair Tool by Microsoft




Microsoft Corporation provides a .NET Framework Repair Tool to Windows users. This tool scans the system for corrupt .NET dependencies and repairs them. It is a portable software that means you need not install it on your PC. Simply double-click on the downloaded file and it will run on your PC. Click Next to start the tool to repair the corrupted .NET dependencies. When the repair process is completed, click Finish and restart your computer.

If this method did not work for you, move ahead to the next one.

3] Run SFC scan on your PC


SFC or System File Checker is a utility for Windows computers provided by Microsoft. It scans the system for corrupted files and repairs them. To perform an SFC scan on your computer, launch the Command Prompt as an administrator and type sfc /scannow, and press Enter.

It may take some time to scan the entire system for corrupted files. When the scan gets completed, restart your computer.

4] Run the DISM scan on your PC


You can deploy .NET Framework 3.5 on your system using the DISM scan. The DISM command-line tool will create a modified image on your system to deploy the .NET Framework version. Launch the Command Prompt as an administrator and type the following command and press Enter.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

The above command will install the .NET Framework 3.5 files from the Windows Update.

Hence, make sure that you are connected to the internet while executing the above command. When the command gets completed, restart your computer.

5] Download .NET Framework offline installer


You can also download .NET Framework offline installer service pack from the Microsoft website. After downloading it, install it on your PC.

Install .NET 3.5 Framework on Windows 10

Is it even possible, the help for this is of no use.

https://support.microsoft.com/en-gb...lation-error-0x800f0906-0x800f081f-0x800f0907

This is the bit thats applicable to me.

To fix the error codes for Windows 10, follow these steps:

1. Download the Windows Media Creation tool, and create an ISO image locally, or create an image for the version of Windows that you have installed.
   
2. Configure the Group Policy as in Method 2, but also follow these steps:
   1. Mount the ISO image that's created in step 1.
   2. Point the "Alternate source file path" to the ISO sources\sxs folder from the ISO.
   3. Run the gpupdate /force command.
   4. Add the .Net framework feature.

Method 2 isn't mentioned anywhere.

Further more if i download the framework installer and run the dotnetfx35setup.exe file i get a window that says it requires the framework its trying to install, so its a loop that requires the framework to install the framework.

Next issue is that if i try to turn it on from Programs and Features in the control panel it throws me back to the initial error of not being able to install it which takes me back to the link above and method for fixing it which doesn't include the information
for Method 2.

I'm starting to think MS are purposely making it uninstallable at this point.

Any help would be much apreciated.

Could someone please make my deleted answer disappear, it's already included in the question, don't remove this line
When I run the .Net Framework 3.5 Installer I get the following error: Windows couldn't complete the requested changes. When I try to enable .Net framework in the command prompt I get the following error:

C:\WINDOWS\Logs\DISM\dism.log

When I go to Windows Features, my list looks like this.

My whole .Net Framework is completely gone.

This is how registry looks like.

My applications like paint.net, discord, UDK, UE4 and Windows Troubleshooter don't work.

I tried to install .net Framework using Server Manager, bu that also requires .Net Framework

UT3 Editor works though

Here is the error I'm receiving:

v4.0

Contact your application publisher for instructions about obtaining the appropriate version of the .NET Framework.

OK

And here are my specs:

To add more important information, in "Control Panel\System and Security\System" System type is "64-bit Operating System, x64 based processor"

Edit: some of my issues have been fixed because Framework 4.8 automatically reinstalled itself by an update, .net 1.1 and 2 are install-able, so it's just waiting until the apps I use add .Net 4.8 Support, Thank you all for your replies!
