Net framework 4 for 64 bit system. What is Microsoft .NET Framework. How do I install and reinstall the NET Framework? Large library base

NET Framework (Dot Net Framework) is a software platform (software framework) developed by Microsoft in 2002, mainly for the Microsoft Windows operating system. Includes extensive libraries and also provides interoperability (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 hardware) known as the Common Language Runtime (CLR), which is a virtual machine that provides security, memory allocation, and exception handling. The class library and CLR together make up the .NET Framework.

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

ATTENTION: be sure to install the service packs in the same order as the links to them are given!

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

You can install this platform in different ways.

• By installing an operating system whose service pack already includes that 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 a game or application is launched, a window of approximate content pops up on the screen: “(application name) requires the presence. NO Framework. Please download and install Net Framework 3.5 or higher. " What makes the launch of 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.

We will be glad to hear from you feedback, we will also help with installing components and fixing errors. Write everything in the comments, just below

".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 the required version of the .NET Framework installer for free. Also, you can find out about the purpose of the .NET Framework, system requirements and familiarize yourself with the instructions for installing or fixing errors related to its operation on different versions of Windows.

Introduction. Why you need .Net Framework

What is .Net Framework? Microsoft .Net Framework- a distributed software platform that 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 (whether it be 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 are taken care of by the .Net Framework

• He is able to 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 operating systems, providing end users with the ability to use any application compatible with this component, regardless of the characteristics of a computer or any other device.

System requirements for optimal performance of the .Net Framework

Hardware requirements for normal operation .Net Framework low enough that the component will work even on the weakest computer. The rest of the information in this chapter is primarily intended for novice users.
The more advanced can move on to the chapter in which you will learn about. Your computer requires:

• Processor with frequency 1 GHZ and higher;
• The amount of RAM is not less than 512 MB;
• Minimum amount of hard disk space in size 4.5 GB.

The .Net Framework has a lot of 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 the package version .Net Framework, on which this or that program was developed will require the corresponding(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 correct version of the .Net Framework, you need to upgrade to a newer version of Windows.
We highly recommend users to install Windows 10.

Determining the bitness 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 capacity of the system.
This information will be required when installing older versions. .Net Framework.
The new libraries are suitable for both OS (x32-x64).

The latest version of the .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 after reviewing 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 the installed updates.

note!

Newest Versions of the .Net Framework do not contain all those libraries that were previously in the old version 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 them to work.

It is also necessary to remember: preinstalled libraries cannot be removed by standard means of the operating system itself.

How to install the correct version of the .Net Framework

Let's say you need an older version of a component to run a specific application.
Usually the software itself notifies the user about the absence of the required version on the OS. .Net Framework by displaying the corresponding error window. An example of such a message is shown in the figure below:

Figure 2. An example of a message about the lack of the required version of the .Net Framework.
In this case, you just need to load the required version of the component for your OS (of course, observing the bit depth) using a special installer, which is of two types:

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

There are no other fundamental differences. When using the stand-alone version of the component, installation errors occur somewhat less often, therefore, when searching, links will most often lead to it. To quickly jump to the download of the required version, go back and click on the title 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)

At the moment (October, 2017) version .Net Framework 4.7 is the last one. Downloading this component completely 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 the .Net Framework 4.7 from our website using a direct link or from the page on the official Microsoft website dedicated to version 4.7 of the component, where you can also find additional information (system requirements, restrictions, etc.)
Version 4.7 supported by the following OS of any bitness (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 a component does not install or does not work properly, read the chapter:.

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

You can read more 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 be missing some features that were previously present in earlier versions.

This happens for various reasons: some components could become outdated, become irrelevant, or they could be replaced by new, more advanced components of the Framework. Some older applications may need exactly those old components that are missing in newer versions, which requires the installation of one of the older versions of the MS .NET Framework. Version 3.5 already includes minor versions of the libraries (so you don't need to download them separately):

• .Net Framework 2.0;
• .Net Framework 3.0.

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

Errors while installing or running .Net Framework

Sometimes incorrect installation or update .Net Framework may cause the component to malfunction. This chapter provides information on various errors that you may encounter at different stages of using the libraries. ".Net".First you need to download the official utility from Microsoft called .Net Framework Repair Tool», Which will automatically help to solve the problem with the component. You will find instructions for this program below.

.NET Framework Repair Tool will find and fix most crashes

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

Microsoft .Net Framework Repair Tool (online version). | 1.22 MB The utility is designed to identify the most common problems when working or installing the .NET Framework, as well as to automatically fix them.

The next time the system starts up, the errors .Net Framework will be corrected, and you can reinstall the required version of the component (if this process was previously accompanied by failures).

If the problem persists during the installation or operation of a component after using the program, read the detailed information on specific errors described in the following chapters.

.Net Framework update installation error 0x80070643 on Windows 7

Error 643 work related "Update Center"... Occurs primarily in Windows 7 users. Attention!
It is recommended to start the steps described below only after familiarizing yourself with the program from the chapter:.
If "Repair Tool" did not find a problem, you should restart Update centre Windows using a ready-made program written specifically for site or using a command algorithm that you can create yourself according to the instructions below.

The executable code is the same in both cases.

The program was created solely for convenience: when using it, you do not have to carry out any manual manipulations. Next, a manual method for restarting the system update will be described.

Follow the further instructions carefully:

1. Create a blank text document and copy the following code into it:

@echo
attrib -h -r -s% windir% \ system32 \ catroot2
attrib -h -r -s% windir% \ system32 \ catroot2 \ *. *
net stop wuauserv
net stop CryptSvc
net stop BITS
ren% windir% \ system32 \ catroot2 catroot2.old
ren% windir% \ SoftwareDistribution SoftwareDistribution.old
ren "% ALLUSERSPROFILE% \ application data \ Microsoft \ Network \ downloader" downloader.old
net Start BITS
net start CryptSvc
net start wuauserv
pause

1. Save the file in extension ".Bat" ;
2. Run the created program as administrator.

On Figure 4 you can take a closer look at the second step.

Figure 4. Save the file in the ".bat" extension.
Now all that remains is to restart the computer and reinstall the installation .Net Framework.

.Net Framework 3.5 installation error: 0x800F0906, 0x800F081F, 0x800F0907 on Windows 8 or 8.1

This issue occurs when trying to install .Net Framework 3.5.Before proceeding with the steps described below, it is recommended that you read the chapter:. Errors 0x800F0906, 0x800F081F, 0x800F0907 in most cases, they appear during the installation of the .NET Framework 3.5, when security updates are installed on the operating system KB2966826 and 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.

The MS developers assumed that users will use new, more current versions of the Framework, and the .NET Framework 3.5 installer itself was created long before these updates, and does not take into account the changes in the policies and security mechanisms that they carry.

To use .Net Framework 3.5 (and below) on new OS, you need:

1. Temporarily disable Windows Update;
2. Delete KB2966826 and KB2966828 through the standard Add or Remove Programs tool;
3. Restart the computer, repeat the installation .Net Framework.

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

Select hard drive and folder to unpack .NET before installation (installer can select drive by itself, like drive A :)

The installer of the latest versions of the .NET Framework selects the drive and destination folder as it sees fit. This may be a rather obscure choice, such as the A: drive, or another drive that is not designed for these tasks.
To work around this problem, just start the installation using the command line (see Figure 5): Figure 5. Installing .NET Framework 4.7.1 with unpacking to a specific folder.

Microsoft .NET Framework Overview
