How to start updating NET Framework. Install or update, correct errors. System requirements for optimal work .NET Framework

I often ask what Microsoft .NET Framework is what this software platform needs, how to check the installed version In the operating system, from where to download and update it, if necessary.

In this article I will try to answer all these questions in simple and understandable language (with pictures).

What is Microsoft .NET Framework

I will not quote you Wikipedia and wake up here with bad definitions - I will explain the purpose of this mysterious bunch software code Literally "on the fingers."

Microsoft .NET Framework is one of the main components for the operating system Windows that must be installed in all users.

I will not quote you Wikipedia and to catch here with dull definitions - I will explain the purpose of this mysterious bunch of the program code literally "on the fingers".

Just imagine "spare parts warehouse" in your computer for a huge number of various programs that can take the "parts" from this "warehouse" at any time and thus unload your installer (installer), make it more compact and fast.

Suppose two of some programs use the same component to work (part of the program code) - why install it twice with each program? And if such utilities are several dozen in the computer? System Disk "End" In this case, very quickly.

This development environment (Microsoft .NET Framework) can be compared with package of universal codecs for video playback or audio files. She also looks very similar to his principle on the general library of DLL files for computer games (DirectX).

The scale of the distribution of our "spare parts warehouse" for programs is very and very huge - almost every second computer program needs this installed in operating system Component. Moreover - it uses all browsers and many sites on the Internet for their proper display and work.

Did the importance of Microsoft .NET Framework in your computer? Go ahead…

How to check the version of Microsoft .NET Framework

Check the installed version of Microsoft .NET Framework in your computer (or availability of it) system registry, without third-party programs.

I will not tell you about this way, because inexperienced users can do a lot of troubles in their registry, if you are distracted for a second and accidentally delete a string or a whole branch (oh, it is itself 🙂).

Moreover, my described below method of checking the version of the Microsoft .NET Framework package is more convenient, visually and more practical.

Check the availability and relevance of one of the most important components of the operating windows systems In my computer, we will with the help of an absolutely free, small and portable ASOFT .NET Version Detector program.

ASOFT .NET Version Detector

After starting this utility you will see, at first glance, an incomprehensible multicolored window ...

... But in fact, everything is very simple. White font shows the software environments already installed on you, and the gray is not installed.

In most cases, the last (newest) package contains the most important parts of previous versions, but there are "especially harmful" programs that submit exactly full version 1.0 or 1.1.

Update Microsoft .NET Framework or download a specific version You can click on the green arrow icon down ...

You will reinforce you on the official page of loading an autonomous installer ...

Such a installer can be copied to a USB flash drive and install on any computer, even without connecting to the Internet.

As you can see in the screenshots at the top - I have the most actual version Microsoft .NET Framework. Modern Windows 10. Very carefully follows it. If you have disabled automatic update Systems or your Operations are not as smart as the "dozen" - ASoft .NET Version Detector will save the position.

Download ASoft .NET Version Detector

Here you have a reference to the official website of the program ...

The size compressed folder With a portable program of only 408 kb.

The search engine issued me in its results in the first place is not the official site and that's what came of it ...

So terrible and wrong verdict I made outdated version Programs downloaded from some "left" site. Here you have the importance official sites computer programs .

Short outcome

How to check and update the version of Microsoft .NET Framework:

1. Download and run the ASOFT .NET Version Detector program
2. Check the scan scan result
3. Click on the green button with an arrow down opposite the missing component
4. Download by the link provided an autonomous installer
5. Run installer to install update

Platform.NET, developed by Microsoft, is an integral part of most games and programs that are running on Windows. In a user understanding, the .NET Framework 4.5 and 4.0 represent the basis for launching programs, in the development of which this platform was used. She has become the standard for developing web applications, because it is not enough likely that you will encounter them incorrect work. In addition, the lack of files of the desired version of .NET Framework can cause the inability to launch games.

Starting with Windows 7, this platform is supplied with the OS distribution, however separate installation maybe you should be needed if there is no computer the desired version, or in the work .Net Framework has failed.

Program version

The most common and necessary today are .NET Framework 4.0 i.NET Framework 4.5. The first comes in the basic package of the OS Windows Vista. And Windows 7, the second - along with Windows 8, however, no matter what kind of system you have, it is better to download and install both versions to avoid problems with the launch of games and programs.

How to find out which version of .NET Framework installed on the computer?

This can be done in two ways:

1. Download and launch ASoft .NET Version Detector from the developer's official website.

1. View B. system Registry. For this:
   • run the registry editor through Start - Run - Regedit;
   • open section HKEY_LOCAL_MACHINE \\ SOFTWARE \\ Microsoft \\ Net Framework Setup \\ Ndp;
   • the names of the branches correspond to the installed versions.

.NET Framework 4.5.

This version comes with microsoft package Visual Studio. 2012. To install it separately, it is enough to download the distribution kit for free .NET Framework 4.5 from the official website and follow the instructions of the installation program.

Net Framework 4.5, as a rule, is missing by default on Windows 7 and it is necessary to load it manually. For this:

• Download .Net Framework 4.5 from the official site Microsoft

• Follow the webloader and installation program instructions.

The installation process is extremely simple, but it is important to remember that more early versions Windows (XP and below) do not support .NET Framework 4.5.

.NET Framework 4.0.

The previous version of the platform, which automatically comes with the Windows 7 distribution, despite the update to version 4.5, it is still relevant. Most applications work without problems with the C.Net Framework 4.5, but some of them may still require the presence of an older version.

In addition, version 4.0 will need you if your OS does not support version 4.5.

The installation process is as simple.

The peculiarity of this development is that it maintains a general-based fulfillment environment. In other words, users will be able to open programs written in different programming languages, as well as develop software (this is interesting to programmers), components of which can be written separately on C #, Delphi or Visual Basic and combined in one application.

Microsoft .NET Framework features:

• interactive customizable interface;
• general-language environment;
• writing programs for Windows (also for Windows Server and Windows Phone);
