Platform NET Framework, along with DirectX, is essential for the functioning of any Windows-system in order to be able to use all the features of the OS to the full, which is usually associated with multimedia or game content. But here is the problem: sometimes NET Framework 4 is not installed. Windows 7 and XP suffer the same crashes more often. Even Vista seems a little preferable in this regard. So what is the reason and how to deal with it?
NET Framework 4 is not installed (Windows 7 and higher): what is the reason?
To begin with, the modification itself in the form of the fourth version is considered obsolete. Today, as a rule, version 4.5 is offered for installation. Apparently, it’s a long wait for the release of a new, fifth modification.
The main reason that the NET Framework 4 client profile and the main components of the platform are not installed is usually called the update problems inherent in the Windows systems themselves. Despite the fact that when the automatic update is activated, the platform should be updated by default, this does not always work. Damage to the Update Center files or installed incomplete packages that cause errors and crashes in the OS can also play a role.
Why isn’t installing NET Framework 4 over version 3.5?
Now one more look at the platform in terms of installing its updates on top of already installed modifications. Why is Microsoft NET Framework 4 not installed? Yes, only because the previous version 3.5, as claimed, is so thoroughly “registered” in the system that the update to version 4 refuses to work.
In general, when installing any modification, the previous version, no matter if it is higher or lower, must be removed. This just saves the user from errors during the installation of higher or lower modifications. Here are just uninstall in the program and component section, which is present in the operating system, is undesirable. The uninstaller does not always delete residual files and registry keys. And this only leads to the fact that the installation program of a different version determines that there is already some kind of 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 uninstall programs that can perform a full check of residual components after the removal of the main program. However, the platform may not be in the list of installed applications, so you will have to use the Windows system components section.
Disabling Updates
In addition to what has already been said, it can be noted that Microsoft NET Framework 4 is also not installed due to 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 exit may be entering the settings of the “Update Center”, disabling the automatic update (it is better to choose the option to offer downloads and installations), as well as uninstalling some packages that are already in the system.
In addition, if NET Framework 4 is not installed (Windows 7 is installed or another system is not important), data overflow in the SoftwareDistribution folder located in the main directory of the system may become overflowing. This directory in the best case you need to rename, just adding something after the main name, or delete. When you restart, it will be created automatically. However, before doing this, updates should be completely disabled. It is also advisable to turn off the Internet connection so that the system does not try to check for updates, citing an official source.
Removing Earlier Platform Versions
As already clear, when moving to a higher modification of the platform, the old one needs to be deleted. 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 search by entering the platform name, and then delete all the keys found. Please 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 Windows Framework does not install NET Framework 4. Everything is simple. The Eshishka is initially oriented towards working with version 3.5, although it even supports installation of 4.5. It is built into it so deeply that it is quite difficult to remove the entire platform using standard methods.
On the other hand, the lack of installed second and third service packs also cannot be ignored. To get rid of the problem, they just need to be integrated into the system. If the user is sure that they are really installed, but the problem arises again and again, you can try to reinstall them again using distributions on removable media or just downloading packages from the official site. But remember: recently, support for XP version by Microsoft has been discontinued. Therefore, a perfectly legitimate question arises: isn’t it easier to upgrade to an OS rank higher? Although you can’t do without formatting here.
Something else
And another problem is that NET Framework 4 is not installed (we take Windows 7 as an example). This may be due to the fact that the user is simply trying to integrate the 64-bit platform into the 32-bit operating system. This does not work, but on the contrary it is possible.
By the way, many users who once encountered such a problem recommend disabling the antivirus for the duration of the installation. How much this helps is not known for certain, but it can be used as one of the options when nothing else helps.
Conclusion
In general, if we draw a line under all of the above, we can say the following: the problem of the fact that the platform sometimes does not want to be installed is, in fact, not a particular problem. It is enough to perform several of the described actions and the errors during the installation of the package will disappear. True, initially you need to try to delete the version of the previous one, and only then apply more cardinal methods. At least something, but it will help. And these are not empty words.
But it is better to refuse to use XP altogether, since this OS is already so outdated that even its creators themselves have denied support.
