Surely many have heard of the Microsoft .NET libraries, which are often the main source of various applications. The interaction between the software that uses it and the libraries themselves is carried out through the .NET Framework system components. Without them, many applications simply won't install.
The current versions of the .NET Framework are considered 4.6 and 4.7 , which also include the old edition 4.5 ... They are built into Windows 10 and you shouldn't have any problems installing or using them. The situation is different with the already outdated version 3.5 ... It was widely used in the days of Windows 7 and is incompatible with the .NET Framework 4.x. Since revision 3.5 is not included with Windows 10 by default, many older programs simply won't install.
How to download and install the .NET Framework 3.5 on Windows 10
The developers have provided an option to install the old version of the .NET Framework in the Windows 10 Component Service. To download the library, you need an Internet connection.
How to download the .NET Framework 3.5 installer for Windows 10
If for some reason you are unable to use the Windows Components Service, you have the option to download and run the .NET Framework 3.5 online installer.
How to install .NET Framework 3.5 without internet (offline)
Occasionally there are problems when using the Windows Update Web Service and users cannot install the .NET Framework 3.5 using the two methods described above. In this case, you can use a bootable USB stick with windows image 10 for manual component installation (no internet connection required).
Therefore, the .NET Framework 3.5 can be installed without using an Internet connection or Windows Update.
".Net Framework" is a special software platform with which a huge number of applications are written for the Windows operating system. For such programs to work, the .NET Framework environment must be installed on your computer.
On this page, you can download the required version of the .NET Framework installer for free. Also, you can find out about the purpose of the .NET Framework, system requirements and familiarize yourself with the instructions for installing or fixing errors related to its operation on various versions of Windows.
Introduction. Why you need .Net Framework
What is the .Net Framework? Microsoft .Net Framework - a distributed software platform that is used to develop modern software.Architecture " .Net ":
- Allows developers not to waste time working out the interaction of the product being created with the environment in which it will be executed (whether it be hardware characteristics, compatibility, OS features or other technical aspects of the environment).
- He is able to work with many programming languages \u200b\u200busing a set of special algorithms, which gives application creators the opportunity to use almost any known principle of constructing program code for their software.
System requirements for optimal performance of the .Net Framework
Hardware requirements for normal operation .Net Framework low enough that the component will work even on the weakest computer. The rest of the information in this chapter is primarily intended for novice users.
The more advanced can move on to the chapter in which you will learn about. Your computer requires:
- Processor with frequency 1 GHZ and higher;
- The amount of RAM is not less 512 MB;
- Minimum amount of hard disk space in size 4.5 GB.
Therefore, for best compatibility with the maximum number of applications, all possible variations of this component should be installed. But this does not mean that the latest libraries will be fully supported by older operating systems.
Sometimes, in order to install a suitable version of the .Net Framework, you need to upgrade to new version Windows.
We highly recommend users to install Windows 10.
Determining the bitness of the operating system: x32 (x86) or x64
Bit depth your operating system (if necessary) you can look in "Properties" computer.
Figure 1. Find out the capacity of the system.This information will be required when installing older versions .Net Framework.
The new libraries are suitable for both OS (x32-x64).
The latest version of the .Net Framework available for installation on your OS
Last .Net Frameworkwhich can be installed on all these OSs (except Windows XP) manually, -this is version 4.7. Before installing the component on your computer, make sure that the version you need is not integrated into the OS defaultafter reviewing the following information:
- Windows XP. Integrated version - 1.0 SP2;
- Windows Integrated Versions - 2.0 SP2, 3.0 SP2and 3.5 SP1;
- Windows 8 or 8.1. Integrated versions - 4.5 and 4.5.1 respectively for these OS;
- Windows Integrated version - 4.6 or 4.6.1depending on the installed updates.
Newest versions of the .Net Framework do not contain all those libraries that were previously in the old version of the .NET Framework.
This means that in order to run some old programs or games, you will have to install the old (!) Versions of the .NET Framework necessary for their operation.
It is also necessary to remember: preinstalled libraries cannot be removed by standard means of the operating system itself.
How to install the correct version of the .Net Framework
Let's say you need an older version of a component to run a specific application.
Usually the software itself notifies the user about the lack of the required version on the OS .Net Frameworkby displaying the corresponding error window. An example of such a message is shown in the figure below:
Figure 2. An example of a message about the missing version of the .Net Framework.
In this case, you just need to load the required version of the component for your OS (of course, observing the bit depth) using a special installer, which is of two types:
- Online (web) installer downloads everything required files .Net Framework from Microsoft servers and independently unpacks the downloaded data. Requires an internet connection.
- Standalone (full)the installer already contains all the libraries you need for a complete installation .Net Framework without internet connection.
Download .Net Framework 4.7 (including versions: 4.6.2, 4.6.1, 4.6, 4.5.2 and 4)
At the moment (October, 2017) version .Net Framework 4.7 is the last one. Downloading this component completely relieves from the need to download the following versions:
- .Net Framework 4.6 (4.6.1 and 4.6.2 );
- .Net Framework 4.5 (4.5.1 and 4.5.2 );
- .Net Framework 4.
Version 4.7 supported by the following OS of any bitness (x32-x64):
- Windows 10 Creators Update (integrated);
- Windows 10 Anniversary Update;
- Windows 8 or 8.1;
- Windows 7;
- Windows Server 2016, 2012 and 2008.
Download .Net Framework 3.5 (including versions: 3.0 and 2.0)
You can read more information and download .Net Framework 3.5 on the Microsoft website or download the library in one file from our website using the links provided.
NET Framework is evolving and newer versions may be missing some features that were previously present in earlier versions.
This happens for various reasons: some components could become outdated, become irrelevant, or they could be replaced by new, more advanced components of the Framework. Some older applications may need exactly those old components that are missing in newer versions, which requires the installation of one of the older versions of the MS .NET Framework. Version 3.5 already includes the younger versions of the libraries (so you don't need to download them separately):
This component is compatible with any currently used operating system from Microsoft, including Windows XP.

.Net Framework 3.5 installation error: 0x800F0906, 0x800F081F, 0x800F0907 on Windows 8 or 8.1
This issue occurs when trying to install .Net Framework 3.5.Before proceeding with the steps described below, it is recommended that you read the chapter:. Errors 0x800F0906, 0x800F081F, 0x800F0907 in most cases, they appear when installing the .NET Framework 3.5, when security updates are installed on the operating system KB2966826 and KB2966828.
This is most likely due to the fact that some Windows updates may not be tested for work or interaction with the .NET Framework 3.5 installer.
The MS developers assumed that users will use new, more current versions of the Framework, and the .NET Framework 3.5 installer itself was created long before these updates, and does not take into account the changes in the policies and security mechanisms that they carry.
To use .Net Framework 3.5 (and below) on new OS, you need:
- Temporarily disable Windows Update;
- Delete KB2966826and KB2966828through the standard Add or Remove Programs tool;
- Restart the computer, repeat the installation .Net Framework.
Selecting hard drive and folder to unpack .NET before installation (installer can select drive itself, like drive A :)
The installer of the latest versions of the .NET Framework chooses the destination drive and folder as it sees fit. This may be a rather obscure choice, such as drive A :, or another drive not designed for these tasks.
To work around this problem, just start the installation using the command line (see Figure 5): Figure 5. Installing .NET Framework 4.7.1 unpacked to a specific folder.
If you just upgraded to Windows 10, you may notice that some programs require earlier versions of Microsoft .NET that are not included in the latest. windows version...
