entranceWhat is blocking microsoft net framework 4. Troubleshooting blocked installations and uninstalls
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 from 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 an opportunity to install 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, 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 mistakes arising during the installation of NET.Framework, want to know if it is possible to do without installing such a package on a computer. Basically, there is no need to overload immediately operating system all kinds of additional applications and programs if the user does not need them. Programmers recommend installing only software that the user needs directly. Overloading the OS 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 the game developers foresee that the game will not be launched without such a platform. In order not to bother the user with additional searches, immediately in boot file games implement and install the platform.
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, the NET Framework 4 Windows 7 is still not installed, displaying a "sad" message on the screen.
The most common cause is a conflict situation that occurs in Windows 7.
Microsoft confirms that the issue resulting from the installation of NO Framework 4 in Windows 7 is indeed related to Center windows updates.
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 work around this error 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 you hear from many users. 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 previous version it can be very difficult to remove, or, in general, there is no way to "get rid" of it.
You cannot ignore this step either, because in the process new installation platforms on Windows 7, an error may occur again.
In order for the entire uninstallation and subsequent installation process to be successful, it is important to follow all the recommendations 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 extension exe... 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 the right to choose Microsoft product to be deleted. Among the proposed list is the line "NET.Framework - all versions", 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 Microsoft versions.NET.Framework. 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, all that remains is to enable Windows Update and then safely install Microsoft.NET.Framework 4.
Despite the fact that you will 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 "gold 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 they believe in own strength and will follow the advice of experienced users.
Good day.
It is not so uncommon to encounter various errors associated with Microsoft package.NET Framework (most often in games, various editors, drawing programs, take at least the same AutoCAD ...).
In all such problems, you need to find out which version of the .NET Framework the application needs, see if it is in Windows, and if it is not there, update / install. It would seem nothing complicated, but there are nuances. They will be discussed in the article ...
For reference. In general, the .NET Framework is a special package that is designed to combine various software written in different programming languages with each other (so that everything works). In theory, you can compare it with codecs. Naturally, if you do not have on your computer the version you want(or it was damaged) - then the program will not start for you.
And now, closer to the point, I will analyze the most basic ...
How do I know which versions of the .NET Framework I have installed?
Method number 1
You need to open the panel Windows management along the following path: (approx. : Installation and removal of programms).
Important!
Note that in Windows 8 and 10, Microsoft .NET is not listed installed programs(to see the versions, you need to open the link in the menu on the left "View installed updates").
There is no option to uninstall .NET in Windows 10 regular means however, it is usually possible to install the latest version of .NET (update it).
Method number 2
To view and solve problems with .NET there is a special utility ".NET Version Detector" (available at the link:).
It doesn't require installation. After launch, it will show a list of all installed versions and will also lead download links (if suddenly something does not appear, you can download and install).
Is it possible not to update this package, because I have not updated it before and everything worked?
Most users do not even remember about it (for the time being ...). The fact is that in the new Windows versions a certain version of .NET is already included in the kit (preinstalled in the system) and there is no need to separately download or update something.
In addition, .NET is often included in the installers of popular games, and when they are installed, this package is also updated. Those. all actions are invisible to the user ...
However, it may be that new program or the game will require a new .NET package (or vice versa, want to run something old that will require a specific version of .NET and no other).
And then everything is simple: if the required version of .NET is not available, then at startup you will see an error (as in the example below). By the way, some of the errors may be related to the "broken" version of .NET (that is why, sometimes it is recommended to update this software).
Firstly, I want to advise right away: you do not need to download all versions in a row and try to reinstall each (a little below I will note which versions are recommended for different OS). Secondly, it is recommended to download .NET only from the official Microsoft website (so to speak, not a modified installer).
Method number 1. A little higher in the article, I recommended you to use the ".NET Version Detector" utility - it will not only show you what versions of the .NET package you have installed on your system, but also provide download links for each version.
- (for Windows XP);
- (includes .NET 2.0, 3.0; for Windows XP, Vista);
- (for Windows XP, Vista and 7);
- (for Windows 7, 8 and 8.1);
- (for Windows 7, 8, 8.1 and 10);
- (for Windows 7, 8, 8.1 and 10).
It is important to note that .NET 4 version (say) upgrades the previous .NET version, so newer Windows 8, 10 OS requires installing (in 99.9% of cases) only the latest .NET 4 versions.
Addition!
I can't help but recommend the program - even if you don't need to update your drivers, try using it anyway. The fact is that it automatically detects missing components in the system that may affect games (.NET, Visual C ++ and other packages), and installs them. Agree, it's convenient!
Please note that the program downloads and installs everything necessary for games (.NET, Visual C ++ and other packages) automatically!
Can I uninstall the .NET Framework (or use a different version)? What does that require?
In most cases, you do not need to remove the package - you just need to use a different version. This can be done in the tab (which can be opened in the Windows Control Panel - just above the article shows you where to find this) .
Actually, you need to put a "tick" next to the package that you want to use and agree to the changes (Windows OS may need to download the missing files - it does it itself in auto mode (just need an internet connection)).
In those cases when you seem to have the required version of .NET installed, but the game (program) still throws errors and "swears" - you can try to uninstall the .NET package and reinstall it.
In some cases, the package can be removed by opening the list of installed programs ( Control Panel \ Programs \ Programs and Features ). Removal occurs in the same way as any other program (see screen below).
In some cases, a special utility may be required: NET Framework Cleanup Tool (link to Microsoft developer blog -).
The utility does not need to be installed. By the way, you need to run it as administrator (approx. : i.e. click on executable file right-click and in context menu select "run as administrator") .
That, in fact, is all for today.
Add-ons are welcome ...
All the best.
The Microsoft .NET Framework is a special component required for many applications to run. This software is perfectly compatible with the operating room. Windows system... Why, then, do errors occur? Let's figure it out.
Why Microsoft .NET Framework might not install
This problem most often occurs when installing the .NET Framework 4 version. There can be many reasons for this.
The presence of an already installed version of the .NET Framework 4
If you don't have .NET Framework 4 installed on Windows 7, the first thing to check is to see if it is installed on your system. This can be done using special utility ASoft .NET Version Detector. You can download it absolutely free on the Internet. We launch the program. After a quick scan, the versions that are already installed on the computer are highlighted in white in the main window.
You can of course see the information in the list of installed Windows programs, but the information there is not always displayed correctly.
The component comes with Windows
V different versions Windows may already have .NET Framework components embedded in the system. You can check this by going to "Uninstall a program-enable or disable Windows components» ... For example, in Windows 7 Starter, Microsoft .NET Framework 3.5 is wired, as you can see in the screenshot.
Windows Update
In some cases, the .NET Framework is not installed if Windows has not received important updates. Therefore, you need to go to "Start-Control Panel-Update Center-Check for Updates"... Any updates found will need to be installed. After that, we reboot the computer and try to install the .NET Framework.
System requirements
As with any program, Microsoft .NET Framework has computer system requirements for installation:
Now let's see if our system complies with minimum requirements... You can see this in the properties of the computer.
Microsoft .NET Framework has been updated
Another popular reason why .NET Framework 4 or more takes a long time to install. early versions, is its update. For example, I updated my component to version 4.5, and then tried to install the 4th version. It didn't work out for me. I received a message that more than a new version and the installation aborted.
Removing various versions of Microsoft .NET Framework
Very often, when you uninstall one of the .NET Framework versions, the rest begin to work incorrectly, with errors. And the installation of new ones generally ends in failure. Therefore, if you are overtaken this problem, feel free to remove the entire Microsoft .NET Framework from your computer and reinstall it.
You can use the .NET Framework Cleanup Tool to properly remove all versions. Setup file you can easily find it on the Internet.
We choose "All version" and press "Cleanup Now"... When the deletion is over, we reboot the computer.
Now you can start reinstalling Microsoft .NET Framework. Be sure to download the distribution from the official site.
Not licensed Windows
Considering that the .NET Framework, like Windows, is a product from Microsoft, a broken version may be the cause of problems. No comment here. Option one - reinstalling the operating system.
That's all, I hope that your problem was successfully solved.
Sometimes programs are not installed or run, referring to the Net Framework of a particular version. The problem can arise for various reasons.
Net Framework is a universal collection of implementations and pieces of code. It is mainly intended for drawing graphics windows programs. Developers use this platform to avoid writing their own code and to have a generic tool. The absence of this component (or its specific type) in the system may lead to the inoperability of some programs.
Why does the error appear
Often times, software installation packages may fail to scan the operating system (OS) or try to put something on top of an existing copy. Sometimes, the problems are much deeper.
The presence of a component in the system
The most common case when Net Framework 4 is not installed is its presence in Windows 7, 8 or 10. Depending on the OS, it may already be installed:
- XP... Does not support installation of Framework with version higher than 3.5;
- 7 ... Pirated assemblies (not clean images from Microsoft) may contain an installation package for a component and install it during system installation;
- 8 and 10... The package is already preinstalled on the system.
You can check the presence of the Framework in the system as follows (for example, Windows 10):
Windows update required
Sometimes, when installing the program, you may see a message stating that it is impossible to install Net component Framework in current state Windows. Usually faced with this Seven users... In this case, you will need start update.
As some programs require the Net Framework, so the framework itself requires some updates on the system. Allowing the system to update is a great solution. True, this can take some time.
Inability to install an outdated version of a component
The most annoying error in installing Net Framework. Some programs do not receive updates for a long time and use a specific function from Microsoft Net Framework 2.0. On Windows XP they work fine, but on Windows 8 they crash.
The problem is that nothing can be done in this case. It's easier to find a replacement for the program. Indeed, "Net Framework 3.5" includes changed command set and outdated solutions have been removed from it. If there is a version No Framework 3.5, the system will block the addition of others. For Windows 7 and 8, you can disable it and perform installation old version libraries, and then include a new one. In Windows 10 - nothing can be done, the possibility of adding is denied by the Microsoft website, and when downloading the package we warn of incompatibilities.
A similar problem can be seen when Net Framework 4.7 is installed on the system. It will just block add 4.
Removed intermediate component
You may also encounter the following problem: when installing previous framework required... For example, installing Framework 2 will uninstall 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 for old ones.
Windows is not licensed
In the absence of a license for the OS, updating and work with components does not work. If there is a message on the screen about need to activate, it is simply impossible to install libraries. First, you need to solve the problem with activation.
Other problems
If during installation none of the above solutions is suitable, then you should go the other way:
- Find and download installation package from the Microsoft website.
- Try install component with his help.
- Find an alternative package installer.
- Try to run.
That's all possible options exhausted.
Long installation
A long-term problem is not a critical problem. Net installation Framework, including 4 versions. It can be the result of preloading and adding updates, or slow download speeds. In this case, you should only be patient and wait until the process is completed. Or try downloading the installation package and using it.
For failed installations of the .NET Framework on Windows 7, this message usually indicates that Windows 7 Service Pack 1 (SP1) is not installed. Windows systems.NET Framework 7 requires Windows 7 Service Pack 1 (SP1). If you are using Windows 7 and have not yet installed Service Pack 1 (SP1), you must do so before installing the .NET Framework.
Program compatibility issues
Installing the .NET Framework 4.5 and its enhanced editions fails with error code 1603 or blocks when running in Windows Program Compatibility Mode. Program Compatibility Assistant reports that the .NET Framework may not have been installed correctly and suggests reinstalling it using the recommended settings (Program Compatibility Mode). It is also possible that Program Compatibility Assistant chose Compatibility Mode if the .NET Framework Setup failed to start or the installation was canceled.
The .NET Framework Installer cannot run in Program Compatibility Mode. To ensure that the installation is not blocked, the system-wide program compatibility mode must be turned off in the registry editor.
HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ AppCompatFlags \ Compatibility Assistant \ Persisted
Click the button Start and select Execute.
In the dialog box Execute type regedit and click OK.
In Registry Editor, locate the following subkeys:
