Removing all frameworks
This method is the most effective, but time-consuming. In order to solve the Microsoft .NET Framework installation error, you need to download the .NET Framework Cleanup Tool.
Good day.
It is not so rare to encounter various errors related to Microsoft package.NET Framework (most often in games, various editors, drawing programs, take at least the same AutoCAD...).
In all such problems, you need to find out which version of the .NET Framework the application requires, see if it is in Windows, and, if not, update/install it. It would seem nothing complicated, but there are nuances. They will be discussed in the article...
For reference. In general, the .NET Framework is a special package that is designed to combine various software written in different languages programming (so that everything works). In theory, you can compare it with codecs. Naturally, if you do not have the required version on your computer (or it has been damaged), then the program will not start for you.
And now, closer to the point, I’ll look at the most important thing...
How can I find out which versions of the .NET Framework I have installed?
Method No. 1
You need to open the panel Windows management along the following path: (approx. : Installation and removal of programms).
Important!
I note that in Windows 8 and 10 Microsoft .NET is not listed installed programs(to view versions, you need to open the link in the left menu “View installed updates”).
There is no option to uninstall .NET in Windows 10 regular means However, as a rule, it is possible to install the latest version of .NET (updating it).
Method No. 2
To view and solve problems with .NET there is a special utility ".NET Version Detector" (available at the link:).
It does not require installation. After launch, it will show a list of all installed versions, and will also lead links to download them (if suddenly something is missing, you can download and install it).
Is it possible not to update this package, since I haven’t updated it before and everything worked?
Most users don’t even remember about it (for the time being...). The fact is that in new Windows versions a certain version of .NET is already included (pre-installed in the system) and there is no need to download or update anything separately.
In addition, .NET is often included in the installers of popular games, and when they are installed, this package is also updated. Those. all actions are invisible to the user...
However, it may happen that new program or the game will require a new .NET package (or vice versa, you want to run something old that will require a certain version of .NET and no other).
And then everything is simple: if the required version of .NET is not available, then upon startup you will see an error (as in the example below). By the way, some errors may be associated with a “broken” version of .NET (which is why it is sometimes recommended to update this software).
Firstly, I would like to immediately advise you: you do not need to download all the versions in a row and try to reinstall each one (a little lower I will note which versions are recommended for different OSes). Secondly, it is recommended to download .NET only from the official Microsoft website (unmodified installer, so to speak).
Method number 1. A little higher in the article, I recommended that you use the ".NET Version Detector" utility - it will not only show which versions of the .NET package you have installed on your system, but also provide links to download each version.
- (for Windows XP);
- (includes .NET 2.0, 3.0; for Windows XP, Vista);
- (for Windows XP, Vista and 7);
- (for Windows 7, 8 and 8.1);
- (for Windows 7, 8, 8.1 and 10);
- (for Windows 7, 8, 8.1 and 10).
It is important to note that version .NET 4 (let's say) updates the previous version of .NET, so new Windows 8, 10 OSes require installing (in 99.9% of cases) only the latest versions of .NET 4.
Addition!
I can’t help but recommend the program - even if you don’t need to update drivers, try using it anyway. The fact is that it automatically detects missing components in the system that may affect games (.NET, Visual C++ and other packages), and installs them. Agree, it’s convenient!
Please note that the program downloads and installs everything necessary for games (.NET, Visual C++ and other packages) automatically!
Is it possible to remove the .NET Framework (or use a different version)? What does that require?
In most cases, there is no need to remove the package - you just need to use a different version. You can do this in the tab (which can be opened in the Windows Control Panel - just above the article shows where to find this) .
Actually, you need to put a checkmark next to the package that you want to use and agree to the changes (Windows may need to download missing files - it does this itself in auto mode (just need an internet connection)).
In cases where you seem to have the required version of .NET installed, but the game (program) still throws errors and “swears”, you can try to remove the .NET package and install it again.
In some cases, a package can be removed by opening the list of installed programs ( Control Panel\Programs\Programs and Features ). Uninstallation occurs in the same way as any other program (see screenshot below).
IN in some cases, may require a special utility: NET Framework Cleanup Tool (link to Microsoft developer blog - ).
The utility does not require installation. By the way, you need to run it as an administrator (approx. : i.e. click on the executable file right click mice and context menu select "run as administrator") .
That's all for today.
Additions are welcome...
All the best to everyone.

The Microsoft .NET Framework is a special component required for many applications to run. This software fits perfectly into the operating room Windows system. Why then do errors occur? Let's figure it out.
Why Microsoft .NET Framework may not install
This issue most often occurs when installing the .NET Framework version 4. There can be many reasons for this.
Availability of already installed version of .NET Framework 4
If you do not have .NET Framework 4 installed on Windows 7, the first thing you need to check is whether it is installed on your system. This can be done using special utility ASoft .NET Version Detector. You can download it absolutely free of charge on the Internet. Let's launch the program. After a quick scan, in the main window those versions that are already installed on the computer are highlighted in white.
You can of course look at the information in the list of installed Windows programs, but the information there is not always displayed correctly.
The component comes bundled with Windows
IN different versions Windows may already have .NET Framework components built into the system. You can check this by going to “Uninstall a program - Turn Windows components on or off”. For example, I have Windows 7 Starter installed with Microsoft .NET Framework 3.5, as you can see in the screenshot.
Windows Update
In some cases, the .NET Framework will not install if Windows has not received important updates. Therefore you need to go to “Start-Control Panel-Update Center-Check for Updates”. Any updates found will need to be installed. After that, we reboot the computer and try to install the .NET Framework.
System requirements
Like any other program, the Microsoft .NET Framework has system requirements computer to install:
Now let's see if our system meets the minimum requirements. You can view this in the computer properties.
Microsoft .NET Framework has been updated
Another popular reason why .NET Framework 4 and earlier versions take a long time to install is because it is updated. For example, I updated my component to version 4.5, and then tried to install version 4. It didn't work out for me. I received a message that my computer has more than a new version and the installation was interrupted.
Uninstalling different versions of the Microsoft .NET Framework
Very often, when you uninstall one version of the .NET Framework, the others begin to work incorrectly and with errors. And installing new ones generally ends in failure. Therefore, if you have suffered this problem, feel free to remove the entire Microsoft .NET Framework from your computer and install it again.
You can correctly remove all versions using the .NET Framework Cleanup Tool. Installation file You can easily find it on the Internet.
Choose "All version" and click "Cleanup Now". When the removal is complete, reboot the computer.
Now you can start Microsoft installation.NET Framework reinvented. Be sure to download the distribution from the official website.
Not licensed Windows
Considering that the .NET Framework, like Windows, is a product from Microsoft, then the broken version may be causing the problem. No comments here. Option one is to reinstall the operating system.
That's all, I hope your problem was resolved successfully.
