Install the Microsoft net framework 4.0 runtime. Install or update, fix errors

Microsoft .NET Framework is a digital platform that allows you to create, launch correctly and use various applications or games, during the creation of which parts of one specific application are written in different program codes. This platform is a digital environment in which different codes of a single application are compiled into one transferable code, which in turn is understandable by the Framework itself. Then the moving code is compiled into understandable code for the operating system for which the application was developed. For example for Windows 7/8/10

You can install this platform in various ways.

• By installing an operating system whose update package already includes this platform.
• Download Net Framework and then install. (Official links on our website)
• Install as additional software when installing the game.
• Install automatically using Windows Update

There are cases: When starting a game or application, a window with approximate content pops up on the screen: “(application name) requires the presence of. NO Framework. Please download and install Net Framework 3.5 or higher." What does startup do? this application impossible without this platform. If you have Microsoft Net Framework 4.7 installed, this does not mean that you do not need older versions. You will need to install both Microsoft Net Framework 4 and previous versions. It is highly recommended to install all existing ones regarding your operating system.

The Microsoft .NET Framework is a component without which some programs may not work. More precisely, it is a platform that provides a wide selection of services for applications that are written for it. It consists of 2 main parts: the CLR (runtime environment for all popular programming languages) and the .NET Framework Class Library (libraries with ready-made functions that can be called from the program).

The main advantages of the .NET Framework for programmers are:

Memory management

In many programming languages, developers are responsible for allocating and clearing memory for objects. In .NET Framework applications, the CLR provides these services on behalf of the application.

Generic Data Types

In traditional programming languages, data types are determined by the compiler, while the .NET Framework makes data types universal across all applications written for it.

Large library database

Instead of writing hundreds or thousands of lines of code to handle common operations, you can use many ready-made functions from libraries.

Convenient development environment

The platform contains libraries for specific areas of application development: ASP.NET for web applications, ADO.NET for databases, Windows Communication Foundation for service applications.

Language Compatibility

Language compilers that create programs for a given runtime “emit” code called Common Intermediate Language (CIL), which is also compiled at run time in the CLR. With this feature, routine codes written in one language can be accessed by other languages ​​and the developer's efficiency increases.

Version Compatibility

With rare exceptions, applications written for earlier versions of the .NET Framework will work fine with newer versions.

Special Requirements

• 1 GHz processor;
• 512 MB of RAM;
• 4.5 GB of free hard disk space.

4.5.2 Final (10.11.2014)

Probably every user of the Windows operating system has come across such a concept as Microsoft .NET Framework, but not everyone knows what it is, what it is for, where to download it and how to install it, so now we will look at all this and install Microsoft .NET Framework 4.0 on Windows 7 as an example.

In addition to everything else, we will learn what the Microsoft .NET Framework 4 Client Profile is and also look at the process of installing it.

We will of course start with the basics, i.e. What is the Microsoft .NET Framework and why is it needed?

What is the Microsoft .NET Framework and what is it for?

.NET Framework is a platform that serves to create and run applications and web services. The developer is Microsoft, so, oddly enough, the .NET Framework was created and designed for the Windows operating system, but there are also projects that allow you to run .NET programs in other operating systems, for example, Linux.

The main components of the .NET Framework are the runtime (CLR) and class library, which includes ADO.NET, ASP.NET, Windows Forms, and Windows Presentation Foundation (WPF). The development environment is primarily Microsoft Visual Studio, which is understandable, since VS development is also a Microsoft company, and in this case the programming languages ​​are: C#, Visual Basic .NET, C++. But just as mentioned above, there are also independent projects in which you can write programs for the .NET Framework in other languages.

For ordinary users, to put it simply, the Microsoft .NET Framework is just a program or component of the operating system, without which programs or games written under the .NET Framework simply will not work, will not even start. Therefore, if anyone doubts whether it is necessary Microsoft program.NET Framework or not, then an answer is, of course, needed, since in the modern world there are a huge number of programs and games that use the .NET Framework libraries. And if you have not yet encountered programs or games that require installation of the Microsoft .NET Framework, then sooner or later you will encounter this. And if we talk about which version to install, then, of course, the newer the better, for example we will install version 4.0, this, by the way, is the latest version of the .NET Framework that can be installed on Windows XP, and the version is available today. NET Framework 4.5.2.

Note! As can be seen from the title of the material, we will install Microsoft .NET Framework 4.0 on the Windows 7 operating system; by the way, by default it already has .NET Framework 3.5 installed, in Windows 8 the default version is 4.0, and in Windows 8.1 it is already 4.5. Therefore, if you have, for example, Windows 8, then you do not need to install .NET Framework 4.0.

Before moving on to the installation, let's talk about the so-called Microsoft .NET Framework 4 Client Profile.

.NET Framework 4 Client Profile

.NET Framework 4 Client Profile is a subset of .NET Framework 4 components that are optimized for client applications. It includes the necessary set of functions and components that are sufficient for most client applications. This includes Windows Presentation Foundation (WPF), Windows Forms, Windows Communication Foundation (WCF). If we talk about what is not included here, then this is: ASP.NET, an extended set of WCF functions, a .NET Framework data provider for Oracle and an MSBuild system for compilation, if you need these components, then you need to already install the full .NET Framework 4. How You probably already understand that the .NET Framework 4 client profile is sort of a stripped-down version of the .NET Framework 4.

And now let's move on to installing these components and we'll start with the Microsoft .NET Framework 4 Client Profile.

Note! If you want to immediately install the full-fledged Microsoft .NET Framework 4.0, then it is not necessary to install the client profile.

Installing Microsoft .NET Framework 4 Client Profile

And in order to install this component, you must, of course, download it, and this can be better done from the official Microsoft download center.

There are two possible installation options: via the web installer, i.e. we downloaded a small program and launched it, and it will already download all the necessary components and the second option is the so-called offline (classic) installation in which we download the full package and then install it. In principle, they are no different, it’s just that with the first option we won’t have some kind of distribution left on our computer, but with the second we will have it. At the same time, we can transfer it and install it on a computer that is not connected to the Internet; in turn, the web installer requires an Internet connection.

I suggest installing the .NET Framework 4 client profile using the web installer, and then using the offline installer when we look at installing the full .NET Framework 4.0.

So, let's begin.

You can download the .NET Framework 4 client profile (web installer) on this page.

You go to the page and click " Download»

You will then be asked to mark for download. additional packages applications, but since in in this case we don’t need anything else, we just click “ Refuse and continue» on the right side of the screen

As a result, you will download the file dotNetFx40_Client_setup.exe, which needs to be launched.

And immediately after launch we need to agree to the license agreement, i.e. check the box next to " I have read and accept the terms and conditions license agreement " and press " Install».

Then we don't need to do anything else, we just wait for the download and installation to finish.

The installation will not take much time, only about 3 minutes, after which the installer will say that “ Installation completed", and we press " Ready».

As you can see, there is nothing complicated in installing the .NET Framework 4 client profile, as well as in installing the Microsoft .NET Framework 4 platform itself, but you will now see this for yourself.

Microsoft .NET Framework- platform developed by the corporation Microsoft to build applications with a beautiful user interface, easy integration and secure communications. In simple terms, Microsoft .NET Framework is a package of components without which many popular applications, games, programs and even drivers refuse to install and work correctly. It should also be noted that each subsequent version of the package .NET Framework, does not replace the previous one, since all versions work independently of each other. To solve this simple problem, it is recommended download and install all the packages listed.

- The necessary assembly of libraries for programming and running applications in Windows.
- Improves the security and performance of applications and your computer.
- Required to run most Windows-based programs.
- Fully work with all versions of Windows OS.
- Installs like a “regular” program.
- Included in the list of the most necessary programs.
- There is support for the Russian language.
