Net Framework 4 is not installed (Windows 7). What to do?

Platform NET Framework, along with DirectX, is extremely necessary for the operation of any Windows-system in order to be able to use all the features of the OS to the fullest, which is usually associated with multimedia or game content. But here's the problem: sometimes NET Framework 4 is not installed. Windows 7 and XP suffer from the appearance of such crashes most often. Even Vista in this respect looks somewhat more preferable. So what's the reason and how to deal with it?

NET Framework 4 is not installed (Windows 7 and higher): what's the reason?

To begin with, the very modification in the form of the fourth version is considered obsolete. Today, as a rule, version 4.5 is offered for installation. The release of a new, fifth modification, apparently, to wait for a long time.

The main reason that the NET Framework 4 client profile is not installed and the main components of the platform are commonly referred to as upgrade problems inherent in Windows systems themselves. Despite the fact that when the automatic update is activated, the platform update should be done by default, this does not always work. Damage to the files of "Update Center" or installed unfinished packages that cause errors and failures in the OS can also play a role.

Why is not NET Framework 4 installed on top of version 3.5?

Now one more look at the platform in terms of installing its updates over already installed modifications. Why is not Microsoft NET Framework 4 installed? Yes, only because the previous version 3.5, it is claimed, is so thoroughly "prescribed" in the system that the update to version 4 refuses to work.

In general, if you install any version of the previous version, no matter whether it's higher or lower, you must definitely delete it. This eliminates the need for errors in the installation process of a higher or lower modification. That's only to perform uninstallation in the programs and components section, which is present in the operating system, it is undesirable. The uninstaller residual files and registry keys do not always delete. And this only leads to the fact that the installer of another version determines that there is already some modification on the computer. Despite the faces, the system begins to "swear".

What is there to do? It is believed that the best option would be to use special uninstaller programs that can perform a full check of the residual components after the main program is deleted. However, the platform may not exist in the list of installed applications, so you'll have to use the Windows system components section.

Disabling Updates

In addition, what has already been said, it can be noted that Microsoft NET Framework 4 is not installed yet and because of the activated automatic update with checking, downloading and installing update packages without the user's knowledge (in the background). Windows 7 suffers from this to the highest degree.

The output can be to enter the "Update Center" settings, disable the automatic update (it is better to choose the option of the download and installation offer), as well as uninstall some packages that are already available in the system.

In addition, if NET Framework 4 is not installed (Windows 7 is installed or another system is not important), the data in the SoftwareDistribution folder located in the main directory of the system may become full. This directory in the optimal version should be renamed, simply adding something after the main name, or delete. When restarting again, it will be created automatically. However, before this update should be completely disabled. It is also desirable to turn off the Internet connection so that the system does not try to check for updates, referring to the official source.

Removing early versions of the platform

As already clear, when upgrading to a higher version of the platform, the old one needs to be removed. If the system does not use uninstallers or optimizers, you can, of course, use standard tools.

But after that, you will need to call the Registry Editor (regedit) and at least just type the search with the platform name, then delete all the keys found. Note that they are usually located in the HKLM branch and its subsections. From user branches, even if records are found, it is not recommended to delete them.

Problems with Windows XP

Finally, a few words about why in Windows XP is not installed NET Framework 4. Everything is simple and simple. "EXpishka" is initially oriented to work with version 3.5, although it supports installation even 4.5. It is embedded in it so deeply that it is quite difficult to completely remove the entire platform using standard methods.

On the other hand, the absence of installed second and third service packs can not be ignored either. To get rid of the problem, they simply need to be integrated into the system. If the user is sure that they are really installed, but the problem occurs again and again, you can try to reinstall them again using distributions on removable media or by simply downloading packages from the official site. But remember: since recent time, support for the XP version by Microsoft has been discontinued. Therefore, a completely legitimate question arises: is not it easier to switch to an OS with a higher rank? Although you can not do without formatting.

Something else

And one more problem that NET Framework 4 is not installed (we take Windows 7 as an example). This may be due to the fact that the user simply attempts to integrate a 64-bit platform into an operating system with a 32-bit architecture. This does not work, but vice versa it is possible.

By the way, many users, who once faced such a problem, recommend disabling the antivirus for the time of installation. As far as it helps, it is for certain unknown, but as one of the options, when nothing else helps, it can be used.

Conclusion

In general, if we draw a line under all of the above, we can say the following: the problem that the platform sometimes does not want to be installed, in fact, is not really a problem. It is enough to perform several described actions, and errors during the installation of the package will disappear. However, initially you need to try to delete the previous version, and only then apply more cardinal methods. At least something, but it will help. And these are not empty words.

But from the use of XP is better to refuse at all, because this OS is already so outdated that even its creators themselves denied support.
