Net framework код ошибки 0x800f0954

Рассказываем, из-за чего возникает и как исправить ошибку 0x800f0954 в Windows 10.

Что это за ошибка?

Этот сбой связан с программным обеспечением .NET Framework. Ошибка появляется во время установки и не дает ее завершить, жалуясь на необходимость подключиться к интернету (даже если он и так есть).

А .NET Framework — это очень нужный инструмент для разработчиков, на базе которого построены многие приложения для Windows. Эти же приложения полагаются на Фреймворк при запуске. Проще говоря, обойтись без него никак нельзя. Поэтому ошибку 0x800f0954 придется как-то исправлять. Иначе есть шанс лишиться кучи программ и видеоигр.

Далее рассмотрим методы решения проблемы, которые уже доказали свою эффективность.

Меняем параметры реестра

Иногда ошибка возникает из-за проблем при подключении к внешнему серверу обновлений. В этом случае можно попытаться установить .NET Framework, игнорируя хранилища Microsoft Update.

Для этого:

• Кликаем по иконке в виде лупы в левом нижнем углу.

• В открывшееся поисковое поле вводим название программы regedit и запускаем ее от имени администратора.

• Когда появится запрос от системы безопасности, нажимаем «Да».

• Откроется реестр. Переходим в нем в папку Windows по пути HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows.
• Кликаем по этой папке правой кнопкой мыши.

• В появившемся контекстном меню наводим курсор на пункт «Создать», а потом выбираем опцию «Раздел».
• Даем ему название WindowsUpdate.

• Потом кликаем правой кнопкой мыши по папке WindowsUpdate и повторяем то же самое. То есть создаем еще один раздел. На этот раз с названием AU.

• Открываем вновь созданный раздел AU. Получится вот такой путь HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU.
• Кликаем правой кнопкой мыши по пустому пространству в правой части редактора реестра.
• В появившемся контекстном меню выбираем опцию «Создать параметр DWORD (32 бита)».

• Даем параметру название UseWUServer.
• Кликаем по нему дважды.

• Появится окошка с настройками. Заменяем «Значение» на 0.

• После этого перезагружаем компьютер и заново пытаемся установить .NET Framework. Ошибка должна исчезнуть.

Удаляем файлы CBS

Второй способ — удаление временных файлов CBS. Это журнал данных Component-Based Servicing. Иногда их наличие мешает установке тех или иных системных компонентов и сторонних приложений.

Чтобы их удалить:

• Открываем встроенный файловый менеджер Windows.
• Переходим в папку _Локальный диск (С:)\Windows\Logs\CBS_
• Удаляем все содержимое. Просто выделяем и жмем на клавишу Delete.
• А потом очищаем корзину.

После удаления журналов пробуем установить .NET Framework через систему выгрузки образов Microsoft. Для этого:

• Открываем поисковик Windows, кликнув по соответствующей иконке.
• Ищем там программу cmd.exe и запускаем от имени администратора.

• Затем вводим команду _Dism.exe /online /enable-feature /featurename:NetFX3 /source:C:_
• Дождавшись окончания работы программы, перезапускаем компьютер.
• А потом еще раз пробуем установить .NET Framework. В этот раз должно получиться.

Устанавливаем .NET Framework через командную строку

Еще один способ обойти ошибку 0x800f0954 — установка .NET Framework прямо с образа системы через командную строку.

Чтобы это сделать:

• Создаем флэшку с установочными файлами Windows (перед этим, вероятно, придется скачать образ Windows 10 с официального сайта Microsoft).
• Вставляем ее в компьютер и запоминаем букву диска, под которой она отображается в системе.
• Открываем поисковик Windows.
• Ищем там командную строку и запускаем ее от имени администратора.
• Сразу же вводим туда команду Add-WindowsCapability -Online -Name NetFx3~~~~ -Source буква диска, под которым записана флэшка с Windows:\sources\sxs

• Дожидаемся, пока завершится процесс загрузки и установки нужных компонентов.
• Затем перезагружаем компьютер и заново пробуем установить .NET Framework стандартным способом.

Устанавливаем дополнительные компоненты

Если у вас установлена Windows 10 Pro (или Enterprise), то есть еще один вариант исправления ошибки. Для этого надо поменять параметры групповой политики в системе.

Чтобы это сделать:

• Одновременно нажимаем клавиши Win + R.
• В окне программы «Выполнить» набираем gpedit.msc и кликаем по кнопке ОК.

• Откроется редактор групповых политик. Переходим там по пути «Конфигурация компьютера»\«Административные шаблоны»\«Система».
• Затем ищем политику под названием «Укажите параметры для установки необязательных компонентов и восстановления компонентов». Кликаем по ней два раза.
• Ставим галочки напротив пункта «Включено» и напротив пункта «Скачайте содержимое для восстановления и дополнительные компоненты непосредственно из центра обновления Windows вместо использования служб Windows Server Update Services (WSUS)»
• После этого перезагружаем компьютер и пробуем заново установить .NET Framework.

When you attempt to install .NET Framework 3.5 or any other optional feature using “Windows Features” (optionalfeatures.exe) dialog or using DISM command-line, error 0x800F0954 may popup.

After enabling .NET Framework 3.5 and clicking OK, the following error may appear:

The same error may occur when attempting to install additional speech recognition or supplemental fonts using Optional features in the Settings page or using DISM command-line. For instance, you run the following command to install .NET Framework 3.5 from an elevated or administrator Command Prompt.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

After pressing ENTER, here is the full error message you might see:

Deployment Image Servicing and Management tool
Version: 10.0.16299.15
Image Version: 10.0.16299.192
Enabling feature(s)
[==========================100.0%==========================]
Error: 0x800f0954
DISM failed. No operation was performed.
For more information, review the log file.
The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

The DISM.log file would show these entries/errors:

xxxx, Info                  DISM   DISM Package Manager: PID=12956 TID=12296 Further logs for online package and feature related operations can be found at %WINDIR%\logs\CBS\cbs.log - CPackageManagerCLIHandler::ExecuteCmdLine
xxxx, Error                 DISM   DISM.EXE: DISM Package Manager processed the command line but failed. HRESULT=800F0954

And the CBS.log file would have recorded these errors:

xxxx, Info                  CBS    DWLD:Failed to do Windows update search [HRESULT = 0x800f0954 - CBS_E_INVALID_WINDOWS_UPDATE_COUNT_WSUS]
xxxx, Info                  CBS    FC:   WindowsUpdateDownloadFromUUP returns. [0x800F0954]

Note that the error 0x800f0954 refers to CBS_E_INVALID_WINDOWS_UPDATE_COUNT_WSUS which indicates that your system might have been configured to use a WSUS server (on your domain network) to get updates instead of connecting to Windows Update servers directly.

If the error 0x800f0954 occurs installing optional Windows features, it may be because the system is unable to access the Windows Update server. This is especially true in case of domain-joined computers which is configured to downloads updates from a WSUS server. It could also be possible that your computer was once a part or a corporate or domain network and the group policy setting is still in place.

Method 1: Bypass WSUS to Install Features/Updates Directly from Windows Update

To fix the problem, temporarily bypass WSUS server using the following registry edit (requires administrator privileges).

1. Right-click Start, and click Run
2. Type regedit.exe and click OK
3. Go to the following registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

4. On the right-pane, if the value named UseWUServer exists, set its data to 0
5. Exit the Registry Editor
6. Restart Windows.

Note: Please note that some servers will flip the UseWUServer back to 1 on reboot. In that scenario, set it to 0, restart the Windows Update service (without rebooting), and install the required optional feature (Feature on Demand).

Set-ItemProperty "REGISTRY::HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate\AU" UseWUserver -value 0
Get-Service wuauserv | Restart-Service
Add-WindowsCapability –Online -Name NetFx3~~~~
Set-ItemProperty "REGISTRY::HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate\AU" UseWUserver -value 1

See if you’re able to install .Net Framework 3.5 or any other optional feature (e.g., Print Management, RSAT, Notepad, etc.) now. In most cases, the above steps should fix the problem.

Method 2: Bypass WSUS for Repair Content/Feature On Demand Downloads

Using this method, you can bypass WSUS server only for downloading repair content and Feature-on-Demand package installation. After you enable the following setting, Windows will use Windows Update (instead of WSUS) to download the FOD packages or the files needed to repair the operating system corruption.

1. Open the Group Policy Editor (gpedit.msc).
2. Go to:

   Computer Configuration → Policies → Administrative Templates → System

3. Double-click “Specify settings for optional component installation and component repair”
4. Set “Download repair content and optional features directly from Windows Update instead of Windows Server Update Services (WSUS)” to Enabled.

(This policy setting specifies the network locations that will be used for the repair of operating system corruption and for enabling optional features that have had their payload files removed.)

Alternately, use the following registry setting equivalent:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Servicing]
"RepairContentServerSource"=dword:00000002

This fixes the error 0x800f0954 when installing a feature (FOD) using GUI or DISM.

Method 3: Install .NET Framework (or Optional Features) from Windows 10/11 ISO or DVD

If the procedure under Method 1 or 2 did not help, you may use the following DISM command (with the installation source path) to install additional features from the Windows 10/11 ISO or DVD.

Here are the steps to install .NET Framework 3.5 from the Windows setup disk or ISO:

1. Obtain the latest Windows 10/11 ISO (assuming that your Windows 10/11 system is running the newest build) using the Media Creation Tool.

   Editor’s note: Even better option would be to update your Windows 10 device fully, and then prepare an up-to-date Windows 10 setup disk by slipstreaming. See how to Slipstream Windows (Integrate Updates with Original Setup Disk)

2. Mount the ISO image by double-clicking on the ISO file.
3. Note down the drive letter of your DVD or the mounted drive, let’s say H:\
   
4. Open an elevated Command Prompt (Administrator) window.
5. Type the following command, and press ENTER

   dism /online /enable-feature /featurename:NetFX3 /Source:H:\sources\sxs /LimitAccess

   

Note: If you need to install the “Windows Communication Foundation (WCF) HTTP Activation” and “Windows Communication Foundation (WCF) Non-HTTP Activation”, make sure you add the /All parameter, as seen in the above screenshot. As said earlier, these two components are usually not required for most users.

Similarly, to install other optional features using DISM, refer blog post Adding features (including .NET 3.5) to Windows 10 – Michael Niehaus’ Windows and Office deployment ramblings as well as Microsoft Docs articles DISM Capabilities Package Servicing Command-Line Options & Available features on demand

Hope this article helped you install .NET Framework 3.5 or any other optional Windows features, without getting the error 0x800F0954.
