.NET Framework is a free application which has now been incorporated into the core Windows package.
Introduced in the late 90’s, as a means to standardize application development across different versions of Windows, it lies at the core of a large number of the most important Windows features.
Unfortunately,.NET framework has been known to cause a large number of errors/problems for many years.
Whilst it doesn’t generally cause the problems itself, it’s often as a result of poor integrations or similar, that they appear.
If you’ve been recommended to “re-install” or “repair”.NET, the following tutorial should help.
Note – .NET cannot be removed.
Because it’s such an integral part of the Windows ecosystem, it’s actually impossible to “remove” the.NET framework from later versions of the system.
Whilst you’re at liberty to update, repair and manage it – removing it doesn’t work.
As such, if you’re experiencing problems, you need to be sure that you have the latest version and that it’s correctly running on your system.
To do this, you need to follow the steps below:
1. Run The Verification Tool
The first step is to run Microsoft’s.NET verification tool.
This is a free piece of software which basically checks for any issues that may be present with.NET.
You’re able to download it by searching for “.NET Verification tool” online, and clicking the first link (it should be a Microsoft web page).
After downloading the tool, run it.
If you don’t know which version of the.NET framework you’re running, just select.NET version 4.
It *should* be the case that the framework should verify (it only really checks to see if the correct files are on the system).
If there are any issues, it will give you an error code which you need to check online… otherwise, continue below.
2. Run The.NET Repair Tool
After doing step 1, you may need to “repair” any of the issues that.NET has.
To do this, you should run the.NET repair tool.
This is another tool created by Microsoft, and essentially allows you to clean up any of the problems that Windows may have with its.NET installation.
Like the verification tool above, you can find it by clicking onto your favourite search engine and looking for “.NET repair tool”.
Click on the first Microsoft link – it should present a page with a big orange button.
Once you’ve clicked the button, download the application to your system and run it.
Follow the steps on screen and restart your PC once completed.
If the above didn’t work, you may want to try updating the framework.
This basically overrides any of the files that may be problematic anyway, allowing you to clean up any errors it may have.
To do this, you will need to do the following:
- Search online for “.NET latest download”
- You should be presented with a Microsoft webpage
- This page will have two options – “.NET Core” & “.NET Framework”
- Click on “Download.NET Framework Runtime” under the.NET Framework option
- Save the file to your PC
- Open it and run it
- It will either tell you if you have the latest version, or prompt you to proceed
- If you can proceed, follow the steps and restart your system
4. Reinstall.NET In “Windows Features”
Lastly, you may be able to remove the feature from Windows Features.
To do this, you need to follow these steps:
- Press “Windows” + “S” keys on your keyboard
- Type “Programs and Features”
- Select the first option (in Windows 10, there may be an option for “Turn Windows features on or off” – which you should click)
- Click onto “Turn Windows features on or off” from the left menu
- From the list, identify “.NET 4.7”
- Uncheck the box
- Click “OK”
- Restart your system
- Open the applet again, and this time check the box
- Windows should perform some installation processes
- Once complete, restart your system again
- Test to see if it worked
If you’re still experiencing issues after following the above, you will need to ensure that any of the applications your system is running are operating correctly. This can typically be achieved by re-installing them.
If you’re out of your depth and are in need of specific support, there are a number of communities online who may be able to help – Reddit, SuperUser and Microsoft Answers being 3 of the most popular. On top of that, you have paid support, which can be found either through Google, locally or on Fiverr.
If you’re still struggling after this, it suggests you have a deeper issue with your system. Although Windows isn’t normally affected by.NET directly, it may be the case that some third party software is conflicting with your OS, leading the errors / problems you’re experiencing to appear. The solution in this instance is to re-install any of the problematic software and ensure that there are no other problems on your system (malware / viruses etc).
