Component comes with windows

In different versions of Windows, the system may already be sewn komponenty.NET Framework. Check it can be enrolled in "Delete Program-Enabling or Disable WINDOVS Components". For example, I have 7 Starter in Windows, sewing Microsoft .NET Framework 3.5, as can be seen in the screenshot.

In some cases. NET Framework is not installed if Windows has not received important updates. Therefore, you need to go to "Startup Control Panel Update Updates". Found updates must be installed. After that, we overload the computer and try to install .NET Framework.

System requirements

Availability of 512 MB. free RAM;

Processor with a frequency of 1 MHz;

4.5 GB. Free scene on the hard disk.

Now we look, whether our system meets the minimum requirements. You can see it in the properties of the computer.

Microsoft .NET Framework has been updated

Another popular reason why is for a long time set .NET Framework 4 and earlier versions, is its update. I for example, has updated its components to version 4.5, and then tried to install 4th version. I did not come out. I received a message that the computer installed a newer version and the installation was interrupted.

Not licensed windows

Taking into account that .NET Framework, like Windows, a product from Microsoft, then the broken version may be caused. Here without comment. Option One - reinstalling the operating system.

That's all, I hope that your problem decided to safely

Sometimes programs are not installed or do not start, referring to the Net Framework of a particular version. The problem may occur for various reasons.

Net Framework - a universal collection implementations and parts of the code. It is mainly designed for recruitment of graphic windows programs. Developers use this platform to not make the code yourself and have a generic tool. The absence of this component (or its specific species) in the system can lead to the inoperability of some programs.

Why an error appears

Often the installation packages may not scan the operating system (OS) or try to put something over the available copy. Sometimes, problems are much deeper.

The presence of a component in the system

The most common case when NET Framework 4 is not installed is the presence of it in Windows 7, 8 or 10. Depending on the OS, it can already be installed:

Xp.. Does not support the Framework setting with a version above 3.5;
7 . Pirate assemblies (not clean images from Microsoft) may contain the component installation package and install it when installing the system;
8 and 10.. The package is already pre-installed in the system.

Check for Framework in the system as follows (on the example of Windows 10):

Windows update required

Sometimes when installing the program, you can see a message that it is impossible to install the NET Framework component in the current state of Windows. Usually faced seven users. In this case, it will be necessary run update.

Some programs require NET Framework and the framework itself requires some updates in the system. An excellent solution is to allow the system to upgrade. True, it can take some time.

The inability to establish an outdated version of the component

The most unpleasant error in installing NET Framework. Some programs do not receive updates For a long time and use a specific feature from Microsoft Net Framework 2.0. On Windows XP, they work normally, but on Windows 8 fly out with an error.

The problem lies in the fact that in this case nothing can be done. It's easier to find a replacement program. After all, in Net Framework 3.5 enters changed command set And outdated solutions from it removed. If there is no version, there is no framework 3.5 in the system will be blocked by adding others. For Windows 7 and 8, you can turn it off and produce it. installing the old version Libraries, and then turn on the new one. In Windows 10 - do nothing it is impossible, the possibility of adding is refuted by the Microsoft website, and when the package is loaded warns about incompatibility.

A similar problem can be seen when NET Framework 4.7 is installed in the system. It just blocked the addition of 4.

Intermediate component removed

You can also encounter such a problem: when installing requires previous framework. For example, installing the framework 2 will be deleted 3. If you then try to install version 4 (or higher) - an error message will appear. Therefore, before installing new options, you need to check the presence of old.

Windows has no license

In the absence of a license on the OS, an update and work with components does not work. If the message is hanging on the screen the need for activation, I am simply impossible to put libraries. First, it is necessary to solve the problem with activation.

Long installation

Not a critical problem is the long installation of NET Framework, including 4 versions. It can be the result of pre-downloading and adding updates or low download speed. In this case, you should only show patience and wait until the process is completed. Or try to download the installation package and use it.

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
