Some users after the update, interested in how and where to download .NET Framework versions 3.5 and 4.5 for Windows 10 — sets of system libraries needed to run some programs. And why these components are not installed, telling about various errors.
In this article, details about the installation .NET Framework in Windows 10 x64 and x86 the hotfix installation errors, and also about where on the official website of Microsoft to download version 3.5, 4.5, and 4.6 (although most likely, these options will not be useful). At the end of the article there is also unofficial way to install data framework, if all the simple options refuse to work.
How to download and install .NET Framework 3.5 in Windows 10 by means of the system
Install .NET Framework 3.5 you can without resorting to official download pages by simply including the corresponding component of Windows 10. (If you have already tried this option but get an error message, also described below the solution).
To do this, go to control panel — programs and features. Then click on the menu item «Enable or disable Windows features».
Check .NET Framework 3.5 and click «OK». The system automatically sets the specified component. Then it makes sense to restart the computer and ready: if some program required to run these libraries, and it should start without related errors.
In some cases .NET Framework 3.5 is not installed and reports any errors with different codes. In most cases this is due to the lack of update 3005628, download which you can on the official page(download for x86 and x64 systems are closer to the end of the page). Additional ways to correct errors you may find in the end of this guide.
If for some reason you require an official installer .NET Framework 3.5, you can download it from the page(we should not ignore that Windows 10 is not in the list of supported systems, all successfully installed, if you use ).
Installation .NET Framework 4.5
As you may have noticed in the previous section instructions in Windows 10 by default enabled feature .NET Framework 4.6, which is in turn compatible with versions 4.5, 4.5.1, and 4.5.2 (might replace them). If for some reason on your system this item is disabled, you can just enable it for installation.
Also you can download these components separately as offline installers from official website:
- — .NET Framework 4.6 (provides compatibility with 4.5.2, 4.5.1, 4.5).
- — .NET Framework 4.5.
If for some reason the proposed installation methods do not work, then there are some additional opportunities to rectify the situation, namely:
- Use official Microsoft utility .NET Framework Repair Tool to repair installation errors. It is available on
- Use Microsoft Fix It utility to automatically fix problems which can lead to installation errors of the system components from here: (in the first paragraph of the article).
- On the same page in the 3rd paragraph it is proposed to load the utility .NET Framework Cleanup Tool completely removes all packages .NET Framework from a computer. This may allow to correct mistakes when re-installing. Also useful if you get a message about that .Net Framework 4.5 is already part of the operating system and installed on the computer.
Informal way to download .Net Framework 3.5 and 4.6 and install it
Many users face the problem that .NET Framework 3.5 and 4.5 (4.6) that are installed through the Windows components 10, or from Microsoft’s website refuses to install itself onto your computer.
In this case, you can try another way — Missed Features Installer 10, which was an ISO image that contains the components present in previous versions of the OS, but missing in Windows 10. Thus, judging by the reviews, installation .NET Framework works.
Just download Missed Features Installer from the official site http://mfi-project.weebly.com/ or http://mfi.webs.com/. Note: built-in SmartScreen filter blocks the download, but as far as I can tell, the downloaded file is clean.
Mount the image in the system (in Windows 10 you can do this simply double click on it) and run the file MFI10.exe. After accepting the license terms, you will see a screen installer.

- (for watching videos and games)
Select .NET Frameworks, and then click to install it:
- Install .NET Framework 1.1 (button NETFX 1.1)
- Enable .NET Framework 3 (sets including .NET 3.5)
- Install .NET Framework 4.6.1 (compatible with 4.5)
Further installation will proceed automatically and, after you restart the computer, program or games that required missing components, should run without errors.
I hope one of the options will be able to help you in cases where .NET Framework is not installed on Windows 10 for some reason.
