How to install an MUI language CAB file in Windows 8.1, Windows 8 and Windows 7

Recently we collected and posted here a bunch of direct links to various MUI language packs for Windows 8.1, Windows 8 RTM and Windows 7. It is useful for users who need to install them on multiple PCs. They will save their Internet bandwidth and time by not downloading them again on each PC. Instead, they can save the offline package and use it for future installs. In this article, we shall see how to install these downloaded language packs.


First, make sure that you have the correct language pack matching your OS.
There are two formats of MUI language packs: EXE, the executable file format, and the CAB (*.cab) file format.
While double clicking the *.exe file is enough to install the appropriate MUI files, installing the CAB files isn't so obvious and requires a few more steps.

Follow these simple instructions to install the CAB files. The process is similar for Windows 8 and Windows 7:

  1. Press Win + R keys together on the keyboard to bring up the Run dialog.
    Tip: see the ultimate list of all Windows keyboard shortcuts with Win keys.
  2. Type the following in the Run box:

    run lpksetup
    Press Enter.

  3. The "Install or Uninstall display languages" wizard will appear on the screen.
    lpksetup wizard
    Click the Install display languages button.
  4. In the next page of the wizard, click Browse and pick the *.cab file of the MUI language you downloaded.
    lpksetup browse
    Wait till it is installed. This can take a considerable amount of time and disk space. A System Restore point will also be created first.
  5. To switch to the installed language pack for your user account, you have to open the following Control panel applet:
    Control Panel\Clock, Language, and Region\Language

    language list

  6. Click the Options link on the right side of the just installed language. There, you will find the ability to activate it as the main display language.
    activate language
    Log out and log in again for the language to change.

    Note: On Windows 7, open Control Panel\Clock, Language, and Region\Region and Language. Click on Keyboards and Languages tab. Under Display language, choose a language from the list and click OK.

That's it. Now you know how to deal with downloaded *.cab files for MUI language packages.

    Any help is appreciated.
