Good day.

It is not so uncommon to encounter various errors associated with 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 needs, see if it is in Windows, and if it is not there, update / install. 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 with each other (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 will analyze the most basic ...

How do I know which versions of the .NET Framework I have installed?

Method number 1

You need to open the panel Windows management along the following path: (approx. : Installation and removal of programms).

Important!

Note that in Windows 8 and 10, Microsoft .NET is not listed in the list of installed programs (to see the versions, you must open the link in the menu on the left "View installed updates").

There is no option to uninstall .NET in Windows 10 regular means, however, as a rule, it is possible to install latest version.NET (update it).

Method number 2

For viewing and solving problems with .NET there is special utility".NET Version Detector" (available at the link:).

It doesn't require installation. After launch, it will show a list of all installed versions, and also lead download links (if suddenly something does not appear, you can download and install).

Is it possible not to update this package, because I have not updated it before and everything worked?

Most users do not even remember about it (for the time being ...). The fact is that in new versions of Windows there is already a certain version of .NET in the kit (preinstalled in the system) and there is no need to separately download or update something.

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 be that new program or the game will require a new .NET package (or vice versa, want to run something old that will require a specific version of .NET and no other).

And then everything is simple: if the required version of .NET is not available, then at startup you will see an error (as in the example below). By the way, some of the errors may be related to the "broken" version of .NET (that is why, sometimes it is recommended to update this software).

Firstly, I want to advise right away: you do not need to download all versions in a row and try to reinstall each (a little below I will note which versions are recommended for different OS). Secondly, it is recommended to download .NET only from the official Microsoft website (not a modified installer, so to speak).

Method number 1. A little higher in the article, I recommended you to use the ".NET Version Detector" utility - it will not only show you what versions of the .NET package you have installed on your system, but will also provide download links for 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 .NET 4 version (say) upgrades the previous .NET version, so newer Windows 8, 10 OS requires installing (in 99.9% of cases) only the latest .NET 4 versions.

Addition!

I can not help but recommend the program - even if you do not need to update the 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!

Can I uninstall the .NET Framework (or use a different version)? What does that require?

In most cases, you do not need to remove the package - you just need to use a different version. This can be done in the tab (which can be opened in the Windows Control Panel - just above the article shows you where to find this) .

Actually, you need to put a "tick" next to the package that you want to use and agree to the changes (Windows OS may need to download missing files- she does it herself in auto-mode (just need an internet connection)).

In those cases when you seem to have the required version of .NET installed, and the game (program) still throws errors and "swears" - you can try to remove the .NET package and reinstall it.

In some cases, the package can be removed by opening the list of installed programs ( Control Panel \ Programs \ Programs and Features ). Removal occurs in the same way as any other program (see screen below).

In some cases, a special utility may be required: NET Framework Cleanup Tool (link to Microsoft developer blog -).

The utility does not need to be installed. By the way, you need to run it as administrator (approx. : i.e. click on the executable right click mice and in context menu select "run as administrator") .

That, in fact, is all for today.

Add-ons are welcome ...

All the best.

Microsoft .NET Framework is the so-called software platform... NET Framework installation is required to run programs written on that platform. To make it clearer for you, I will explain as follows: some video files will not play in windows if the necessary codecs are not installed for them. The situation is the same here: programs written under the NET Framework cannot be executed if this component is not installed on the system.

An important point: for the operation of an application written for a specific NET version Framework, this version is required to be installed.

Microsoft released the first version of the NET Framework back in 2000, and since then there have been several (NET Framework 1.0, 1.1, 2.0, 3.0, 3.5, 4.0, 4.5).

How do you know which versions of the NET Framework are installed on your computer?

The easiest way is to download and run the small ASoft .NET Version Detector program.

After launching in the program window, you will see three multi-colored rectangles, which show all existing versions of the NET Framework. The versions installed on your computer are highlighted in white, and those that are not installed are highlighted in gray: If you click on the green arrow on the left opposite the required version, you will be taken to the Microsoft website, where you can download this version of the NET Framework.

You don't need to click on the purple arrow - this is the link to the .NET Developer Toolkit.

If you click on the third from the left edge of the icon (in the form of the logo "Microsoft NET"), then a folder on your computer will open in which the NET Framework is installed.

Where to download and how to install Microsoft .NET Framework?

In different versions of the operating system windows already embedded different versions NET Framework. For example, Windows 7 includes version 3.5 SP1. In turn, this version includes NET Framework 2.0 with SP1 and SP2 and NET Framework 3.0 with SP1 and SP2.

Windows 8 includes NET Framework 4.5.

Installing Microsoft The .NET Framework is extremely simple and does not require any specific settings: just download the required package and run its installation. Below are the links where you can download the required version of the NET Framework:

Microsoft .NET Framework 1.0 Version 1.0 is almost never used, and installation is rarely required.

Microsoft .NET Framework 1.1 Version 1.1 is rarely used, install only when necessary.

Microsoft .NET Framework 3.5 Service Pack 1 Setup file version 3.5 SP1 also includes versions 2.0 SP2 and 3.0 SP2.

Microsoft .NET Framework 4.0

Microsoft .NET Framework 4.5.1 Is an update to versions 4.0 and 4.5, so if you install 4.5.1, then these versions do not need to be installed. windows XP is not supported by NET Framework 4.5.

How do I reinstall Microsoft .NET Framework?

Sometimes the system has problems, one way or another related to the NET Framework. For example, errors appear when starting some programs or when installing (updating) the Microsoft .NET Framework itself. In this case, the most reliable solution to problems is to remove the platform and reinstall it.

To correctly remove NET Framework from your computer, it is best to use the specially designed .NET Framework Cleanup Tool.

Download it here, then unzip the archive and run cleanup_tool.exe.

A message appears: "Are you running the .NET Framework Setup Cleanup Utility?" (though in English) - click "Yes". Then accept the terms of the license agreement (“Yes” button). In the program window, select the “.NET Framework - All Versions” item in the list and click the “Cleanup Now” button:
After remove NET Framework, restart your computer. Then reinstall the versions you want, starting with the smallest one.

In the user's understanding, .Net Framework 4.5 and 4.0 represent the basis for launching programs in the development of which this platform... It has become the standard for developing web applications, so if you don't have it, there is a high probability that you will encounter them incorrectly. In addition, the lack of files for the correct version of the .NET Framework can cause the games to fail to run.

Starting with windows 7, this platform is bundled with the OS distribution, but a separate installation may be required if the required version is missing on the computer, or the .NET Framework has crashed.

Program versions

The most common and necessary ones today are .NET Framework 4.0 and .NET Framework 4.5. The first one comes in the basic configuration of the OS windows vista and windows 7, the second - along with windows 8, however, regardless of which system you have, it is better to download and install both versions in order to avoid problems with launching games and programs.

How do I know which versions of the .NET Framework are installed on my computer?

NET Framework 4.0

The previous version of the platform, which is automatically supplied with the windows 7 OS distribution kit. Despite the update to version 4.5, it is still up-to-date. Most applications work without problems with the .NET Framework 4.5, however some of them may still require an older version.

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

The installation process is just as simple:

Download the web installer from Microsoft official site

Download and install the .NET Framework on windows 7

What is the mysterious .NET Framework for ordinary users? This is a proprietary Microsoft programming model designed to develop a variety of programs. The .NET Framework is needed both for developing programs and for running them.

Therefore, if a programmer actively creates a program in a particular version of the .NET Framework, the user cannot run it until the correct version of the .NET Framework is installed.

Disgusting, we understand. However, everything is not so scary, since the required version of the .NET Framework is installed by default in windows 7. However, more on that later.

For now, let's take a look at the existing versions of the .NET Framework.

.NET Framework version 1.0 and 1.1

Version 1.0 has long been outdated and, in fact, is not used. The same applies to version 1.1, which needs to be installed only in very rare cases, when some ancient programmer requires it.

To install .NET Framework 1.1, you need to download it from the link below, then install. Do this only if absolutely necessary - most windows users 7, you do not need to download this version.

Download .NET Framework 1.1

It may happen that you receive error messages while installing the .NET Framework 1.1 and SP1. In such a situation, the .NET Framework 1.1 can be manually installed as follows.

1. On the C: drive, create a Fix folder (C: \ Fix).

2. Download the .NET Framework 1.1 and Service Pack 1 to this folder.

3. Open command line(you must be running with an administrator account). To do this, click on the Start button, enter cmd in the search field and click.

4. Enter the following two commands.

Cd / d C: \ Fix dotnetfx.exe /c:"msiexec.exe / a netfx.msi targetdir = C: \ Fix "

5. Confirm the execution of the commands and enter the following three commands.

NDP1.1sp1-KB867460-X86.exe /xp:C:\Fix\netfxsp.msp msiexec.exe / a c: \ Fix \ netfx.msi / p c: \ Fix \ netfxsp.msp netfx.msi

The .NET Framework 1.1 package should now install without error.

.NET Framework 2.0 - 3.5.1

This version is installed by default in windows 7, which is easy to see for yourself. Select Start> Control Panel> Programs and Features, and then click the Turn Windows features on or off link. And here's proof that .NET Framework 3.5.1 is installed by default on windows 7:

.NET Framework Version 4.0

This version is necessary, first of all, for programmers and is rarely required to run client programs. However, to run software created in .NET Framework 4.0, you can (and should) install the KB982670 update, which has long been distributed through windows service Update. Over time, there will be more and more programs that require this version of the .NET Framework.

You can download the .NET Framework 4.0 from the following links. We remind you that full version the .NET Framework 4.0 option only needs to be downloaded for software development! If you regular user, you need a regular, client version of the .NET Framework 4.0 - client profile-update KB982670, which you should download via windows Update.

However, if you download the full version of the .NET Framework from the first link and install it, nothing bad will happen - just the system will be replenished with a bunch of unnecessary files that you do not need at all.

What version of the .NET Framework do I have?

You can check this in the Turn windows 7 components on or off window shown above. However, there are other options as well.

2. Or open the editor system registry(Start> regedit and click), then go to the next branch, which will indicate the installed versions of the .NET Framework.

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ NET Framework Setup \ NDP

As you can see, nothing complicated. We remind you that the .NET Framework, the most common and useful version 3.5.1, is installed by default in windows 7, so before downloading it - check that you should already have it installed.

Currently, the vast majority of common software applications used in Windows environment 10 require a Microsoft product called the .NET Framework. This platform allows the operating system to transform software applications compiled in other programming languages, making them available for understanding directly in Windows 10. Sometimes the platform may experience some failures, leading to the impossibility of the newly installed programs. To fix errors of this kind, it becomes necessary to reinstall the .NET Framework or update the platform.

Features of Microsoft NET Framework in Windows 10

In Windows 10, the Microsoft .NET Framework is built in by default and is installed at the same time as the operating system. In some cases, it becomes necessary to reinstall or update the platform to change working version... This is extremely rare, since licensed Windows 10, installed on a computer with Internet access, contains almost everything Microsoft versions.NET Framework, including the latter.

The most common problem for computers that do not have access to global network: to reinstall or update the Microsoft .NET Framework version on such devices, you need to download it from the official Microsoft website and install it on the required computer using a portable media.

Which Microsoft NET Framework to Install on Windows 10

The latest version of the Microsoft .NET Framework presented by Microsoft on the official website and recommended for work in Windows 10 is version 4.7. It is installed automatically when installing the operating system via the Internet or from a licensed media. In addition, version 3.5 is automatically installed, including versions 2.0 and 3.0.

Thus, there is no need to change anything in the settings, since all previous versions included in the latter. Problems can occur only on computers that do not have access to the Internet, or on computers with pirated copies of Windows 10. In this case, you can install version 3.5 of Microsoft .NET Framework.

All of these variations will work correctly in the Windows 10 operating environment.
