".NET Framework" - This is a special software platform with which a huge number of applications for the Windows operating system is written. To work such programs, it is necessary to surround the.NET Framework to be installed on your computer.

On this page you can download the desired version of the installer .NET Framework. Also, you will be able to learn about the destination.NET Framework, system requirements and read the installation instructions or correcting errors associated with its work on various versions of Windows.

Introduction Why need .NET Framework

What is .NET Framework? Microsoft .NET Framework. - distributed software platform, which is used to develop modern software.Architecture " .NET ":

Allows developers not to spend time on working out the interaction of the product being created with the environment in which it will be performed (be it hardware characteristics, compatibility, OS features or other technical aspects of the environment).

All nuances to create a comfortable working environment for application or software takes on themselves .NET Framework

Able to work with many programming languages \u200b\u200bwith a set of special algorithms, which gives applications creators the ability to use almost any well-known principle for building a program code for their software.

In other words, .NET Framework. It becomes the database to start applications on various OS, providing end users with the ability to use any applications compatible with this component, regardless of computer characteristics or any other device.

System requirements for optimal work .NET Framework

Requirements for hardware components for normal operation .NET Framework. Low enough, so the component will work even on the lowest computer. Further information in this chapter is first of all for novice users.
More advanced can go to the chapter in which you will learn about. From your computer required:

Processor with frequency 1 GHz and higher;
The amount of RAM is not less 512 MB;
Minimum number of hard disk space 4.5 GB.

.NET Framework has enough versions, which are available since Windows XP, but there were no major changes in the component architecture. Remember that the package version .NET Framework.on which the program was developed to require appropriate(2, 3, 4 ) Version on your computer.
Therefore, for better compatibility with the maximum number of applications, all possible variations of this component must be installed. But this does not mean that the newest libraries will be fully supported by the old OS.
Sometimes to install the appropriate version of .NET Framework, you need to upgrade to the new version of Windows.
We highly recommend users to install Windows 10.

Determination of the discharge of the operating system: x32 (x86) or x64

Bigness your operating system (if necessary) you can see in "Properties" Computer.

Figure 1. Review the bit of the system.
This information will be required when installing old versions. .NET Framework..
New libraries are suitable under OS of both discharges (x32-x64).

The latest version of.Net Framework available to installation on your OS

Last .NET Framework.which can be set to all of these OS (with the exception of Windows XP) manually, -this is version 4.7. Before installing the component on the computer, make sure that the version you need is not integrated into the OS defaultAfter reading the following information:

Windows XP. Integrated version - 1.0 SP2.;
Windows Integrated Versions - 2.0 SP2, 3.0 SP2and 3.5 SP1;
Windows 8 or 8.1. Integrated versions - 4.5 and 4.5.1 accordingly for these OS;
Windows Integrated Version - 4.6 or 4.6.1depending on the installed updates.

note!

The newest versions of .NET Framework do not contain all those libraries that were previously in the old version .Net Framework.
This means that to start some old programs or games you have to install the necessary for their work, old (! ).Net Framework.

It is also necessary to remember: the preset libraries cannot be removed by the staff of the operating system itself.

How to install the desired version of .NET Framework

Suppose you needed an earlier version of the component to start a specific application.
Usually the software itself notifies the user about the absence of the required version. .NET Framework.Displaying the corresponding window with an error. An example of such a message is shown in the figure below:

Figure 2. An example of the message of the required version of .NET Framework.
In this case, it is necessary to simply download the desired version of the component under your OS (naturally, observing the discharge) using a special institutewhich happens two types:

Online (web) Installer downloads all the necessary files. .NET Framework. From Microsoft servers and independently unpacks loaded data. Requires an Internet connection.
Autonomous (full)the installer already contains all libraries that are needed for a full installation. .NET Framework. without connecting to the Internet.

There are no other principal differences. When using the autonomous version of the error component, the installation occurs slightly less, so when searching for the link, it will most often be on it. To quickly go to download the desired version, go back and click on the title with the name of the component you need.

You can familiarize yourself with additional information. .NET Framework 3.5 On the Microsoft website or download the library with one file from our site using the presented links.

NET Framework develops, and in its new versions there may be no some components that were previously present in earlier versions.

This is happening for various reasons: some components could be outrage, become not relevant, or new, more advanced framework components could come to change. Some old applications may need exactly in those old components that are missing in new versions, which requires installing one of the old MS .NET Framework. Version 3.5 Already includes the younger versions of libraries (so you do not need to download separately):

.NET Framework 2.0;
.NET Framework 3.0.

This component is compatible with anyone now used by the operating system from Microsoft, including with Windows XP.. Installation .NET Framework 3.5 In most cases, it will allow to run and ensure the normal operation of any old program or play.

Installation or work errors .NET Framework

Sometimes incorrect installation or update .NET Framework. It may entail failures in the component. This chapter provides information on various errors with which you may encounter at different stages of using libraries. ".Net".First you need to download the official utility from Microsoft called ".NET Framework Repair Tool", Which in automatic mode will help solve the problem with the component. Instructions for this program you will find below.

.NET Framework Repair Tool will find and eliminate most failures

According to Microsoft, this utility solves problems when working and installing or updating any version .NET Framework..

Now it remains only to restart the computer and reinstall the installation. .NET Framework..

Error Installation Platform.net Framework 3.5: 0x800F0906, 0x800F081F, 0x800F0907 on Windows 8 or 8.1

This problem occurs when you try to install .NET Framework 3.5.Before performing the actions described below, it is recommended to familiarize yourself with the chapter :. Errors 0x800F0906, 0x800F081F, 0x800F0907 In most cases, it is manifested when installing.NET Framework 3.5, when security updates are installed in the operating system KB2966826. and KB2966828..

Most likely it is due to the fact that some Windows updates may not be tested to work or interact with the.Net Framework 3.5 installer.

MS developers proceeded from the fact that users will use new, more relevant versions of the framework, and the Framework 3.5 installer itself was created long before these updates, and does not take into account the changes in the security policies and the safety mechanisms that they carry.

To use.NET Framework 3.5 (and below) on new OS, it is necessary:

Temporarily disable "Windows Update Center";
Delete KB2966826.and KB2966828.through the standard "Install and Remove Programs";
Reload the computer, repeat the installation .NET Framework..

After installing the component, you can turn on automatic updates back.

Select a hard disk and folder for unpacking .NET before installation (the installer can select the disk itself, for example. A :)

Installer of the latest versions .NET Framework selects the disk and the destination folder to its discretion. This can be quite not an obvious choice, for example, a C drive A:, or another disk that is not intended for these tasks.
To get around this problem, it is enough to start the installation using the command line (see Figure 5): Figure 5. Installation .NET Framework 4.7.1 with unpacking into a specific folder.

Microsoft .NET Framework. - This is the so-called software platform. Net Framework is required to perform programs written on this platform. In order for you to be clearer, I will explain as follow: Some video files will not be played in Windows if they do not have the necessary codecs for them. Here is the same situation: programs written by Net Framework will not be able to be executed if this component is not installed in the system.

Important moment: For the application written under the specific version of Net Framework, you need to install exactly this version.

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

How to find out which versions of Net Framework are installed on your computer?

Microsoft .NET Framework 4.5.1
It is updated version 4.0 and 4.5, so if you install 4.5.1, you do not need these versions. Windows XP is not supported by NET Framework 4.5.

How to reinstall Microsoft .NET Framework?

Microsoft .NET Framework is a digital platform that allows you to create, correctly start and use various applications or games, when creating which parts of one particular application are written by different software codes. This platform is a digital environment in which different codes of the separate application are compiled into one passing code, which in turn is understood by the Framework platform itself. Then the switching code is compiled into a clear code for the operating system directly, which the application was developed. For example for Windows 7/8/10

Install this platform can be established in various ways.

By installing the operating system, the package of updates of which already includes this platform.
Download Net Framework and then install. (Official links on our site)
Install as an additional software when installing the game.
Automatically install using the Windows Update Center

There are cases: that during the startup of the game or application, the approximate content window pops up on the screen: "(application name) requires the presence of a framework. Please download and install Net Framework 3.5 or higher. " What makes the start of this application impossible without this platform.
