Hi all! When installing some computer toys On a laptop with Windows 10, I have already encountered the error several times: “ The application on your computer requires the following Windows component: .NET Framework 3.5(includes .NET 2.0 and 3.0)". P« When I try to download and install the component I get an error Windows could not find the files needed to make the requested changes. Error code 0x800F081F " or "» An error has occurred. Some components could not be installed

. The most common solution to this problem, which is offered on the Internet, does not help.

".Net Framework" is a special software platform with which a huge number of applications are written for the Windows operating system. For such programs to work, the .NET Framework environment must be installed on your computer.

On this page you can download for free the required version.NET Framework installer. Also, you can learn about the purpose of the .NET Framework, system requirements and read the instructions for installing or fixing errors related to its operation on different versions of Windows.

Introduction. Why do you need .Net Framework

What is the .Net Framework? Microsoft .Net Framework– distributed software platform, which is used to develop modern software. Architecture « .Net":

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

All the nuances of creating a comfortable working environment for an application or software is taken over by the .Net Framework

It can work with many programming languages using a set of special algorithms, which gives application creators the opportunity to use almost any known principle of constructing program code for their software.

In other words, .Net Framework becomes the basis for running applications on various OSes, giving end consumers the opportunity to use any applications compatible with this component, regardless of the characteristics of the computer or any other device.

System requirements for optimal performance of the .Net Framework

Requirements for hardware components for normal operation .Net Framework low enough that the component will work even in the most weak computer. The rest of the information in this chapter is primarily intended for first-time users.
Those more advanced can skip to the chapter where you will learn about. Your computer is required to:

Processor frequency 1 GHz and higher;
The amount of RAM is at least 512 MB;
Minimum amount of hard disk space in size 4.5 GB.

The .Net Framework has quite a few versions that have been released since the days of Windows XP, but there have been no major changes in the architecture of the component. Remember that the package version .Net Framework, on which this or that program was developed will require appropriate(2, 3, 4 ) version on your computer.
Therefore, for best compatibility with the maximum number of applications, all possible variations of this component should be installed. But this does not mean that the latest libraries will be fully supported by older operating systems.
Sometimes, in order to install the appropriate version of the .Net Framework, you need to upgrade to new version Windows.
We strongly recommend that users install Windows 10.

Determining the bit depth of the operating system: x32 (x86) or x64

Bit depth your operating system (if necessary), you can look in "Properties" computer.

Figure 1. Find out the system capacity.
This information will be required when installing older versions .Net Framework.
The new libraries are suitable for operating systems of both bit sizes (x32-x64).

Latest version of .Net Framework available for installation on your OS

Last .Net Framework, which can be installed on all these OS (except Windows XP) manually - this is version 4.7. Before installing a component on your computer, make sure that the version you need is not integrated into the OS default by reading the following information:

Windows XP. Integrated version – 1.0 SP2;
Windows Integrated Versions – 2.0 SP2, 3.0 SP2 And 3.5 SP1;
Windows 8 or 8.1. Integrated versions – 4.5 And 4.5.1 respectively for these OS;
Windows Integrated Version – 4.6 or 4.6.1 depending on installed updates.

note!

Latest versions of .Net Framework do not contain all those libraries that were previously in older versions of the .NET Framework.
This means that in order to run some old programs or games, you will have to install the old(!) versions of the .NET Framework necessary for their operation.

Also remember: pre-installed libraries cannot be removed regular means the operating system itself.

How to install the correct version of .Net Framework

Let's assume that you needed an earlier version of the component to run specific application.
Usually software automatically notifies the user that the required version is not available on the OS .Net Framework, displaying the corresponding error window. An example of such a message is shown in the figure below:

Figure 2. Example of a message about the missing version of the .Net Framework.
In this case, you simply need to download the required version of the component for your OS (observing the bit depth, of course) using a special installer, which comes in two types:

Online (web) The installer downloads all the necessary files .Net Framework from Microsoft servers and independently unpacks the downloaded data. Requires an Internet connection.
Autonomous (full) the installer already contains all the libraries that are needed for a full installation .Net Framework without an internet connection.

There are no other fundamental differences. When using the standalone version of the component, installation errors occur somewhat less frequently, so when searching, links will most often lead to it. For quick transition to download the required version, go back and click on the header with the name of the component you need.

Download .Net Framework 4.7 (including versions: 4.6.2, 4.6.1, 4.6, 4.5.2 and 4)

On this moment(October, 2017) version .Net Framework 4.7 is the last one. Download this component in full relieves from the need to download the following versions:

.Net Framework 4.6 (4.6.1 And 4.6.2 );
.Net Framework 4.5 (4.5.1 And 4.5.2 );
.Net Framework 4.

You can download .Net Framework 4.7 from our website using a direct link or from the page of the official Microsoft website dedicated to the version of the component 4.7, where you can also familiarize yourself with additional information(system requirements, restrictions, etc.)
Version 4.7 supported by the following OS of any bit depth (x32-x64):

Windows 10 Creators Update (integrated);
Windows 10 Anniversary Update;
Windows 8 or 8.1;
Windows 7;
Windows Server 2016, 2012 and 2008.

If the component does not install or does not work correctly, read the chapter: .

Download .Net Framework 3.5 (including versions: 3.0 and 2.0)

You can check out additional information and download .Net Framework 3.5 on the Microsoft website or download the library in one file from our website using the links provided.

NET Framework is evolving, and newer versions may lack some components that were previously present in older versions. earlier versions.

This happens for various reasons: some components could become outdated, become no longer relevant, or they could be replaced by new, more advanced components of the Framework. Some older applications may require exactly those old components that are missing in new versions, which requires installing one of the older versions of the MS .NET Framework. Version 3.5 already includes minor versions of libraries (so there is no need to download them separately):

.Net Framework 2.0;
.Net Framework 3.0.

This component is compatible with any currently used Microsoft operating system, including Windows XP. Installation .Net Framework 3.5 in most cases, it will allow you to launch and ensure normal operation of any old program or game. However, if you are experiencing problems with this version of the component, please review the information in the next chapter.

Errors during installation or operation of the .Net Framework

Sometimes incorrect installation or update .Net Framework may result in component malfunctions. This chapter provides information on various errors that you may encounter at different stages of using libraries.

Errors 0x800F0906, 0x800F081F, 0x800F0907 in most cases appear when installing .NET Framework 3.5, when security updates are installed on the operating system And KB2966826.

KB2966828

This is most likely 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 assumed that users would use new, more current versions

Framework, and the .NET Framework 3.5 installer itself was created long before these updates, and does not take into account the changes in policies and security mechanisms that they bring.

To use .Net Framework 3.5 (and below) on new OSes, you must: Temporarily disable;
"Windows Update" in most cases appear when installing .NET Framework 3.5, when security updates are installed on the operating system And Delete KB2966828 through standard remedy
"Installation and removal of programms"; .Net Framework.

Restart your computer and repeat installation After installing the component, you can turn it back on.

automatic updates

The installer of the latest versions of the .NET Framework selects the destination drive and folder at its discretion. This may be a rather non-obvious choice, such as drive A:, or another drive not designed for these tasks.
To get around this problem, just run the installation using the command line (see Figure 5): Figure 5. Installation of .NET Framework 4.7.1 with unpacking into a specific folder.

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.

NET Framework (Dot Net Framework) is a software platform (software framework) developed by Microsoft in 2002, mainly for the operating system Microsoft Windows. Includes extensive libraries, and also provides cross-compatibility (each language can use code written in other languages) of several programming languages. Programs written in the .NET Framework run in a software environment (as opposed to a hardware environment) known as the Common Language Runtime (CLR), which is a virtual machine, which provides security, memory allocation, and exception handling. The class library and CLR together make up the .NET Framework.

The .NET Framework core class library provides access to user interface, data exchange, database connectivity, cryptography, web application development, computing algorithms and network connections. Programmers create their applications by linking their own code with the .NET Framework libraries as well as other libraries. The .NET Framework is intended to be used by most new applications being developed.
