Windows 7 and 8.1 systems must be installed with integrated version 4.5 of the .NET Framework, which is required for some programs and games to work properly. And Windows 10 should initially on board contain a preinstalled version of the 4.6 platform, compatible with the predecessor version 4.5. The old version of the .NET Framework 3.5, which is required to run, as a rule, is not supported by the developers of programs and games for a long time. current versions Windows is not included. Naturally, this means that the operating system was installed from the original distribution image. With non-original distributions, everything can be different: the operating system can either contain several versions of the .NET Framework, including the old 3.5, or be delivered without separate preinstalled system components like a stripped-down Windows assembly.

The old .NET Framework 3.5 is installed as a separate stage when installing programs based on the architecture of this platform version into the system. The installation of the latter can also be started manually by the user. What needs to be done for this? We open the control panel. In the window of the latter, we are looking for the "Programs and Features" section. To make it faster, in Windows 7, the title of the section can be registered as a search query in the search bar of the Start menu. And in Windows 8.1 and 10, direct access to this section is provided in the menu invoked by the Win + X keys. In the window that opens, click on the link shown in the screenshot below.

A small window will appear with a list of system components. Here you need to activate the checkbox of the .NET Framework 3.5 version and click "OK".

However, the process of downloading and installing the platform will not be successful in every case.

How are problems that might arise during the installation of the .NET Framework 3.5 resolved?

1. Downloading the installer from the Microsoft website

If the .NET Framework 3.5 is not installed using the above method, you can try to resolve the issue by running the platform installer that you downloaded.

2. Starting the Update Service

The platform installation error 0x800F081F, as a rule, is a consequence of previously disabling the Center service Windows updates... If system updates were disabled or, perhaps, special tweaking programs were used in Windows 10 for these purposes, you need to start the Center service. The system services section can be opened using the Run command. In its field is entered:

At the very bottom of the list of services is the service of the Center. Open it with a double click.

We start the service. Apply the changes.

After that, you must try to install the platform again using any of the methods discussed above.

3. Using DISM

NET Framework 3.5 installation issues discussed above require an Internet connection. If there is no Internet connection, you can use the Windows distribution kit to install the software platform. The method described below is also suitable for cases when an error message 0x800F0906 is received when trying to install the platform.

We connect the distribution kit of the version of Windows that is installed on the computer. Either we connect a USB flash drive, or insert a DVD into the drive, or mount the ISO image into a virtual drive. Windows versions 8.1 and 10 among the standard functionality provide for the ability to mount ISO images and display them as disk partitions. For this in context menu on the ISO file of the Windows distribution, select "Connect".

Before further actions, you need to establish how the distribution media appears in the explorer. Then in command line paste the copied command:

DISM / Online / Enable-Feature / FeatureName: NetFx3 / All / LimitAccess / Source: D: \ sources \ sxs

We correct the command: instead of the drive letter D, as in the above example, we substitute our own letter for a flash drive, DVD-disk or mounted ISO image. We press Enter.

After the progress of the command reaches 100%, we can close the command line and try again to install the platform as described at the beginning of the article.

Have a great day!
