Language packs are no longer available after you upgrade to Windows 8.1 from Windows 8

Symptoms

After you upgrade from Windows 8 to Windows 8.1, language packs that were installed before the upgrade are no longer available. You can still switch to the keyboard layout of the languages that were installed before the upgrade. However, the only available display language is the base language version of the Windows installation. In some cases, you cannot reinstall the language packs or change the display language of Windows.

Cause

This behavior is by design. Language packs are not upgraded as part of the operating system upgrade. This issue occurs because Windows 8 and Windows 8.1 each have version-specific language packs. When you upgrade Windows 8 to Windows 8.1, the operating system reverts to its base language version. After the upgrade is finished, you have to reinstall any language packs that you require. 

It is also possible that the Advanced language options are set to cause Windows to use a display language that is not yet installed after the upgrade. This causes a condition that prevents you from being able to change the display language or download language packs.

Resolution

Follow Resolution 1 to install the language packs. If you have issues downloading or installing language packs, please go to Resolution 2. 

Resolution 1: Install the language packs

The instructions for installing language packs can be found in the following Microsoft Knowledge Base article:
Download a language pack from the Windows website

Language packs are sometimes unavailable, and you cannot download them in Control Panel. If you experience this issue, try to find and download the language pack that you want on the following Windows website: If you cannot download a management pack, please go to Resolution 2.

Resolution 2: Change settings that may block installation

There are advanced language settings that may block the download of language packs. To revert these settings to their defaults values so that you can download language packs, follow these steps:
  1. Open Control Panel. To do this, type Control Panel in the Search box, and then tap or click Control Panel in the search results list.
  2. Tap or click Clock, Language and Region. (If you are viewing Control Panel in icon display, select Language, and then go to step 4.)
  3. Tap or click Language.
  4. Tap or click Advanced settings.
  5. Examine the Override for Windows display language and Override for default input method lists. Make sure that the Use language list (recommended) option is selected for both lists (see Figure 1). Then, tap or click Save.

  6. After you save the settings, you are returned to the standard language settings. In the list of previously installed languages, click Options next to the language you want to install.
  7. Click the download link to install the language pack (see Figure 2).

    Note After the installation is finished, you are prompted to restart the computer.
