"Initialization error" connected with the inability to use the component. There may be several reasons for this. It occurs at the stage of launching games or programs. Sometimes users see it when they start Windows. This error has nothing to do with hardware or other software. Occurs directly in the component itself. Let's take a closer look at the reasons for its appearance.
Why does the Microsoft .NET Framework error "Initialization error" occur?
If you see such a message, for example, when starting Windows, it means that some program is at startup and accesses a Microsoft .NET Framework component, which in turn gives an error. It is the same when launching a certain game or program. There are several reasons and solutions to the problem.
Microsoft .NET Framework not installed
This is especially true after reinstalling the operating system. Not all programs require the Microsoft .NET Framework component. Therefore, users often do not pay attention to its absence. When a new component-enabled application is installed, the following error occurs: "Initialization error".
You can view the installed .NET Framework component in "Control Panel-Add or Remove Programs".
If the software is really missing, just go to the official website and download the .NET Framework from there. Then we install the component like a regular program. We reboot the computer. The problem should go away.
Incorrect component version installed
Looking at the list of installed programs on the computer, you find that the .NET Framework is there, and the problem still occurs. Most likely the component needs to be updated to the latest version. You can do this manually by downloading the required version from the Microsoft website or using special programs.
A small utility ASoft .NET Version Detector allows you to quickly download the required version of the Microsoft .NET Framework component. Click on the green arrow opposite the version of interest and download it.
Also, using this program, you can view all versions of the .NET Framework installed on the computer.
After the update, the computer should be rebooted.
Microsoft .NET Framework component corruption
The last reason for the error "Initialization error"may be due to damaged component files. This may be the result of viruses, improper installation and removal of a component, cleaning the system with various programs, etc. In any case, Microsoft .NET Framework must be removed from the computer and reinstalled.
To properly uninstall Microsoft .NET Framework, we use additional programs, such as the .NET Framework Cleanup Tool.
We reboot the computer.
Then, download the required version from the Microsoft website and install the component. After, restart the system again.
After the manipulations, the Microsoft .NET Framework error: "Initialization error" should disappear.
We accept the terms of the license agreement and click "Next".
The installation of the utility will start.
After that, diagnostics will start, search and fix the problem.
After completing the operation, click "Finish" and restart the PC.
Self-service troubleshooting
To solve this problem yourself, you need to manually remove all frameworks, download and install new ones. To do this, click "Start", "Control Panel", "Programs", "Remove Programs".
Find and remove frameworks.
After that, you need to run the Microsoft Fix It utility, which will check if there are any .NET Framework components left on the computer. Download and run the utility, accept the terms of the license agreement. From the menu that appears, select "Identify problems and install fixes (recommended)".
After clicking "Delete" and click "Microsoft .NET Framework" and "Next".
Run the utility until the name "Microsoft .NET Framework" disappears from the list.
Then go to the site http://net-framework.ru/ and download the necessary distributions.
Removing all frameworks
This method is the most effective, but time-consuming. In order to resolve the Microsoft .NET Framework installation error, you need to download the .NET Framework Cleanup Tool.
Microsoft .NET Framework Is the so-called software platform. NET Framework installation is required to run programs written on that platform. To make it clearer for you, I will explain as follows: some video files will not play in Windows if the necessary codecs are not installed for them. The situation is the same here: programs written under the NET Framework will not be able to execute if this component is not installed on the system.
An important point: for an application written for a specific version of the NET Framework to work, the installation of this particular version is required.
Microsoft released the first version of the NET Framework back in 2000, and since then there have been several (NET Framework 1.0, 1.1, 2.0, 3.0, 3.5, 4.0, 4.5).
How do you know which versions of the NET Framework are installed on your computer?
Microsoft .NET Framework 4.5.1
It is an update to versions 4.0 and 4.5, so if 4.5.1 is installed, then these versions do not need to be installed. Windows XP is not supported by NET Framework 4.5.
How do I reinstall Microsoft .NET Framework?
Sometimes the system has problems, one way or another related to the NET Framework. For example, errors appear when starting some programs or when installing (updating) the Microsoft .NET Framework itself. In this case, uninstalling the platform and reinstalling it will be the most reliable solution.
To correctly uninstall NET Framework from your computer, it is best to use a specially created program for this .NET Framework Cleanup Tool.
Download it, then unpack the archive and run the file cleanup_tool.exe.
A message appears: "Are you running the .NET Framework Setup Cleanup Utility?" (though in English) - click "Yes". Then accept the terms of the license agreement (“Yes” button).
In the program window, in the list, select “.NET Framework - All Versions” and click the “Cleanup Now” button: 
After you uninstall NET Framework, restart your computer. Then reinstall the versions you want, starting with the smallest one.
For those who, at least in the slightest degree, understands computer software, it is absolutely clear that in any case there comes a time when it becomes necessary to install NET.Framework.
Users often have problems installing and using NET.Framework
This is not surprising at all, since NET.Framework is a framework on which you can build and then later run some applications. Since Microsoft is the developer of such a platform, it is, of course, designed for Windows, although there is still the possibility of installing NET.Framework on some other operating systems, including Linux.
Unfortunately, the installation of the platform is not always successful, users have to face serious problems when system errors occur, due to which the installation process ends with a sudden failure.
Of course, the question immediately arises why Microsoft NET Framework 4 is not installed. Having received an answer to this question, you can find ways to fix the problem.
Inexperienced users who have heard about possible errors that occur during the installation of NET.Framework want to know if it is possible to do without installing such a package on a computer. In principle, there is no need to immediately overload the operating system with all sorts of additional applications and programs if the user does not need them. Programmers recommend installing only software that the user directly needs. Excessive loading of the OS with unnecessary programs provokes a shortage of free space on the hard disk, which degrades both the operation of the system and its performance.
By the way, Microsoft originally included the NET.Framework download in the Windows 7 installation package. In addition, the loading of the platform can also be automatically carried out if the user wants to install some game applications, since in this case, game developers foresee that the game will not be launched without such a platform. In order not to bother the user with additional searches, the installation of the platform is immediately introduced into the boot file of the game.
Errors encountered
Having figured out the algorithm for installing new software, users, by analogy, proceed to install NET.Framework on Windows 7. By following all the proposed actions in sequence, the user reassures himself that everything will go unambiguously smoothly, and soon the platform will be successfully installed on Windows 7, after which you can immediately start downloading and then launching your favorite game.
However, in some cases there is disappointment, because you have to face the fact that even if you strictly follow the instructions, you still cannot install NET Framework 4 Windows 7, displaying a “sad” message on the screen.
The most common cause is a conflict situation that occurs in Windows 7.
Microsoft confirms that the problem resulting in NO Framework 4 not installing in Windows 7 is indeed related to Windows Update.
Of course, if a problem arises, then there is someone who is trying to find ways to solve it. So in this case, programmers have already found effective ways to get around the error that occurs by successfully installing NET.Framework on Windows 7.
At the same time, there is no need to do something incredible, the algorithm for eliminating the problem is detailed, so even those who do not have sufficient practical experience can master it.
How to install NET.Framework
“I can't install the NET Framework” is a phrase that many users hear. The combination "I can not" just flooded thematic forums. Fortunately, there are programmers who, thanks to their excellent knowledge and practical skills, are able to find various options for eliminating errors. In addition, they do not hide their ingenious "findings", but are happy to share with everyone, so on the forums you can often find valuable advice that allows even absolute "dummies" to solve problems.
Algorithm of actions focused on platform installation
To install NET.Framework on Windows 7, you must first remove the previous installation traces of all versions. It is quite difficult for inexperienced users to do such manipulations, since Microsoft has tightly "intertwined" system folders with platform folders. For this reason, the previous version can be very difficult to remove, or, in general, there is no way to "get rid" of it.
It is also impossible to ignore this step, because during the new installation of the platform on Windows 7, an error may occur again.
For the entire uninstallation and subsequent installation process to be successful, it is important to follow all the recommendations of experienced users. First of all, it is recommended to download the dotnetfx_cleanup_tool.zip file. Next, it should be opened, and then immediately extracted, since it is placed in the archive.
In the folder where all the extracted files are located, you need to find the cleanup_tool file with the exe extension. It should be launched. A new window will immediately appear, in which permission is requested for all subsequent actions. By clicking on the "Yes" button, the user agrees with everything, so the program continues to perform all other actions.
At a certain moment, a window will appear in which you will be offered the right to select the Microsoft product that you want to remove. Among the proposed list is the line "NET.Framework - all versions", by selecting it, it remains to click on the "Clear" button.
However, even such an application is not omnipotent, since it will not be able to remove NET.Framework 2.0, since this version of the platform is defined by Microsoft developers as an integral part of the operating system.
After cleaning is complete, the computer must be restarted. Microsoft developers put forward such requirements for many important procedures associated with the installation and uninstallation processes.
After starting the operating system, several versions of Microsoft.NET.Framework should be installed sequentially. Initially version 1.1, then proceed to installing versions 3.5 and 3.0, then you will need to restart your computer again.
In the end, it remains to enable Windows Update and after that, safely install Microsoft.NET.Framework 4.
Despite the fact that you have to spend some time performing all the indicated actions, the user can definitely be proud of the result. New knowledge, backed up by practical skills, is always viewed as a "golden treasure" that can be useful many times over.
So, every user can install the NET.Framework 4 platform on a computer, despite some difficulties, if he believes in his own strength and follows the recommendations of experienced users.
