Windows systems The .NET Framework 7 requires Windows 7 Service Pack 1 (SP1). If you are using Windows 7 and have not yet installed SP1, you must do so before installing the .NET Framework.
Program compatibility issues
Installation of the .NET Framework 4.5 and its enhanced editions fails with error code 1603 or blocks when it is run in compatibility mode Windows programs.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's also possible that the Program Compatibility Assistant chose compatibility mode if the .NET Framework installer failed to run or the installation was canceled.
The .NET Framework installer cannot be run in Program Compatibility Mode. In order for the installation not to be blocked, the program compatibility mode for the entire system must be turned off in the registry editor.

The Microsoft .NET Framework is a special component required for many applications to run. This software is perfectly compatible with operating system Windows. Why then do errors occur? Let's figure it out.
Why Microsoft .NET Framework might not install
This issue most commonly occurs when you install the .NET Framework version 4. There can be many reasons for this.
Having .NET Framework 4 already installed
If you do not have the .NET Framework 4 installed on Windows 7, the first thing to check is if it is installed on the system. This can be done using special utility ASoft .NET Version Detector. You can download it absolutely free of charge on the Internet. We start the program. After a quick scan, those 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 installed programs Windows, but there the information is not always displayed correctly.
The component comes with Windows
in different Windows versions.NET Framework components may already be embedded into the system. You can check this by going to "Uninstall a program - Turn Windows features on or off". For example, in Windows 7 Starter, I have Microsoft .NET Framework 3.5, 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". Found updates will need to be installed. After that, we reboot the computer and try to install the .NET Framework.
System requirements
Like any other program, the Microsoft .NET Framework has system requirements computer to install:
Now let's see if our system matches minimum requirements. You can see it in the properties of the computer.
Microsoft .NET Framework has been updated
Another popular reason why it takes a long time to install .NET Framework 4 and more early versions, is its update. For example, I updated my component to version 4.5, and then tried to install the 4th version. I didn't get anything. I received a message that my computer has more than a new version and the installation aborted.
Removing various versions of the Microsoft .NET Framework
Very often, when removing one of the versions of the .NET Framework, the rest start 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 install it again.
You can properly uninstall all versions using the .NET Framework Cleanup Tool. Installation file you can easily find it on the internet.
Choose "All version" and click "Cleanup Now". When the removal is over, we reboot the computer.
Now you can start Microsoft installation.NET Framework again. Be sure to download the distribution from the official site.
Not licensed Windows
Given that the .NET Framework, like Windows, is a product from Microsoft, a broken version can be the cause of problems. There are no comments here. Option one is to reinstall the operating system.
That's all, I hope that your problem has been successfully solved
Sometimes programs won't install or run due to net framework one version or another. The problem can occur for various reasons.
Net Framework is a universal collection of implementations and parts of code. It is mainly intended for rendering graphics windows programs. Developers use this platform to avoid coding on their own and have a generic tool. Absence this component(or a specific variant of it) on the system may cause some programs to fail.
Why does the error appear
Often, software installation packages may not scan the operating system (OS) or try to put something on top of an existing copy. Sometimes, the problems go much deeper.
Presence of a component in the system
The most common case when Net Framework 4 is not installed is 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 pure images from Microsoft) may contain a component installation package and install it during system installation;
- 8 and 10. The package is already preinstalled in the system.
You can check the presence of the Framework in the system as follows (on Windows example 10):
Windows update required
Sometimes, when installing a program, you can see a message stating that it is impossible to install the Net Framework component in the current state of Windows. Usually faced with Seven users. In this case, you will need run update.
As some programs require the Net Framework, the framework itself requires some updates in the system. The perfect solution is to let the system update. True, this may take some time.
Inability to install an obsolete version of a component
The most annoying error in Net Framework installation. Some programs not receiving 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 with an error.
The problem is that in this case, nothing can be done. It's easier to find a replacement for the program. After all, Net Framework 3.5 includes modified instruction set and obsolete solutions were removed from it. If there is a version of No Framework 3.5, the system will block the addition of others. For Windows 7 and 8, you can disable it and produce 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 incompatibility.
A similar issue can be seen when Net Framework 4.7 is installed on the system. It will just block adding 4.
Removed intermediate component
You may also encounter the following problem: when installing previous framework required. For example, installing Framework 2 will remove 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 the presence of old ones.
Windows is not licensed
In the absence of a license for the OS, updating and working with components do not work. If a message appears on the screen about the need for activation, it is simply impossible to install libraries. First you need to solve the activation problem.
Other issues
If none of the these decisions, 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
Not a critical problem is the long installation of Net 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 to download the installation package and use it.
For those who have even the slightest understanding of 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 upon which you can build and then subsequently run some applications. Since Microsoft is the developer of such a platform, it is certainly designed for Windows, although it is still possible 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 it is not installed Microsoft Net Framework 4. Having received the answer to this question, you can find ways to fix the problem.
Inexperienced users who have heard about the possible errors that occur when installing 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. OS overload unnecessary programs provokes a shortage of free space on the hard disk, which worsens both the operation of the system and its performance.
By the way, Microsoft initially bundled NET.Framework into the Windows 7 installation package. In addition, the loading of the platform can also be automatically carried out if the user has a desire to install some gaming applications, because 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 embedded in the game's boot file.
Encountered errors
Having understood the algorithm for installing a new software, users, by analogy, proceed to install NET.Framework on Windows 7. By performing all the proposed steps in sequence, the user reassures himself that everything will go smoothly, and soon the platform will be successfully installed on Windows 7, after which you can immediately start downloading and subsequent launch favorite game.
However, in some cases, disappointment arises, because you have to face the fact that even if you strictly follow the instructions, the NET Framework 4 Windows 7 still does not install, 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 that does not install NO Framework 4 in Windows 7 is indeed related to the 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, the programmers have already found effective ways to work around the error by successfully installing NET.Framework on Windows 7.
At the same time, there is no need to do something incredible, the algorithm for fixing the problem is described in detail, 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’t” 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 brilliant “finds”, 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 the installation of the platform
To install NET.Framework on Windows 7, you must first remove all previous installation traces of all versions. It is quite difficult for inexperienced users to do such manipulations, since Microsoft company tightly enough "twisted" 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 can’t ignore this step either, because during the new installation of the platform on Windows 7, an error may occur again.
In order for the entire process of uninstallation and subsequent installation 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 the .exe extension. That is what should be launched. A new window will immediately appear asking permission 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 some point, 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 there is a line "NET.Framework - all versions", selecting it, it remains to click on the "Clear" button.
However, such an application is not omnipotent, since it will not be able to remove NET.Framework 2.0, since this version of the framework is defined by Microsoft developers as an integral part of the operating system.
After cleaning is completed, the computer must be restarted. Microsoft developers put forward such requirements for many important procedures related to the installation and uninstallation processes.
After starting the operating system, install several versions of Microsoft.NET.Framework in sequence. Initially version 1.1, then go to the installation of versions 3.5 and 3.0, then again you will need to restart the computer.
In conclusion, it remains to enable Windows Update and after that safely install Microsoft.NET.Framework 4.
Despite the fact that it will take some time to perform all the indicated actions, the user can definitely be proud of the result. New knowledge, supported by practical skills, is always considered as a “golden treasure”, which can be useful many more times.
So, despite some difficulties, every user will be able to install the NET.Framework 4 platform on a computer if they believe in own forces and will follow the recommendations of experienced users.
