Latest version of net framework. We install or update, fix errors. System requirements for optimal performance of the .Net Framework

The Microsoft .NET Framework is a software framework that supports the creation and execution of other desktop and web applications on Windows OS since build 98.

The main focus of this platform is the compatibility of various applications written in different languages programming.

It is recommended that you download and update the Microsoft .NET Framework Windows users who encounter errors during the installation of any programs or games.

Platform features:

• allows you to achieve compatibility between services written in different languages ​​and environments;
• independently take care of basic security, memory management and the list of exceptions while working with programs;
• identifies and loads only those components that are applicable and necessary for a particular system;
• does not require any settings from the computer user.

Purpose creation of Microsoft The .NET Framework was intended to give developers of various software maximum freedom of action for their creativity.

The Microsoft .NET Framework allows most programs to run on modern Windows operating systems. Therefore, its installation will be necessary for all users. Microsoft, starting from the operating room Windows systems 7, includes this tool in the distribution and installs it automatically during installation.

Download NET Framework 3..

Do not care about the language in which a particular utility is executed, its architecture, system bitness or assembly - the mission is about application compatibility various types it was decided to rely on this software environment.

The principle of completing the task in stages:

1. Start a service or process.
2. The compiler converts the language being used into a single bytecode.
3. Execution or translation of code for a specific target process or service.

You need to understand that the latest version of the Microsoft .NET Framework does not replace the previous one in all cases. It is also important that new builds operating systems Windows families do not support older versions of this tool.

Microsoft NET Framework upgrade to latest version Recommended for all users of Windows OS 7, 8 and 10 of any bit size.

So, if 4.0 is installed, but not 3.5, and the program needs exactly the previous one, then it will not start working without the necessary one. At the same time, 3.5 already includes 2.0 and 3.0, so sometimes it is better to install it. And XP from Microsoft supports software platform only up to 4.0. Therefore, when installing, for example, a game that requires a new Microsoft version.NET Framework, you will have to reinstall the entire OS or look for another alternative to the game.

It is worth noting that Microsoft does not recommend that users install multilingual versions of this software on their PCs. software environment. In such cases, conflicts are possible and incorrect work utilities If the need arises, it is better to remove the already installed one and install a new one.

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 programming languages ​​(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 Windows Control Panel using 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 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 new versions of Windows already have a certain version of .NET 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.
