Language Support and Configuration

With respect to language support, Adobe provides the following installers:

Verifying language support

In addition to the installer’s filename, you can also check the setup file directory which includes the language specific .mst files. These are identified by language ID codes.

Pre-deployment configuration

Methods for specifying the product language include:

  • Install a single language installer.
  • Install a multi language installer (MUI or non-English which also includes English), and let the end user select the language.
  • Set the language with the Customization Wizard. Refer to Installation Options > Language selection.
  • Set the language with command line properties.
  • Specify whether a MUI application should use the OS language by setting bUseMUI to 1 as described in the Preference Reference.
  • Specify both the language code and the language-specific MST on the command line. For example, to deploy a Dutch version of the product, use:
msiexec /i <path\AcroPro.msi> LANG_LIST=en_US TRANSFORMS="1043.mst;<other MSTs if needed>"  /qb

Multilanguage installers

All Acrobat DC installers are MUI installers. Reader is also provided in a MUI version. MUI installers provide a way to install the product with support for more than one language. Features include:

  • Support for more than one language so that users can switch languages.

  • Automatic selection of the language based on the language of the current OS.

  • The MUI installer for Acrobat on both Windows and Macintosh provide the following benefits to enterprise IT and OEM vendors:

    • A reduction in the number of Acrobat installers from twenty to two (1 each for Pro and Standard).
    • For those supporting multiple locales, one or two downloads (as opposed to up to 20) and a simpler patching and update workflow.
    • Smaller patch sizes. In 10.0 and earlier, Acrobat patches needed to provide separate files for 20 installers. 11.0 and later MUI installers use fewer files.
    • Simplified licensing: Both Windows and Macintosh use a limited number of serial number types to specify the product language.

The base installer is an MSI file, and MSP patches are also periodically released which can only be applied over the base mui MSI install. Both installers are identified by “_mui” in the filename.

Note

MUI installers are only created in tandem with full MSI installers. They are not created for MSP updates and patches. What this means for your deployment methodology is that you simply install the generic installer over your MUI install if there is a no MUI-specific installer. If there is a MUI-specific installer, you must use that. Download the MUI installer from ftp.adobe.com/pub/adobe/reader/.

The MUI Reader always contains the base English resources. To support another language, an additional resource bundle is added to the installation. Therefore, English is always present, and the single language Reader is about the same size as the MUI Reader.

The installation size varies with the type of install:

  • Bootstrapper (setup.exe) or UI-based installer: The size is significantly larger than the single language version because the full installer is kept on the disk.
  • AIP install: Except for minor differences in some of the text files, the size of the MUI Reader will be about the same as the single language Reader.

Windows MUI installers

Windows MUI installers for Acrobat behave as follows:

  • All serial numbers are language based.

  • There are two types of serial numbers: one for all languages and one for a single language.

  • The installer gets the language attributes from the serial number.

  • English is always installed in addition to any specified locale.

  • End user installs with a retail non-MUL serial number do not provide additional language options at install time.

  • Language specification occurs as follows:

    • An “all language” serial number installs Acrobat in the OS language (Typical Installation).
    • A “single language” serial number installs Acrobat in the specified language
    • End users can choose any combination of languages to be installed via a custom installation.
    • End users will be able to install one or more languages via the Installer Repair/Modify option.
    • The LANG_LIST property can be used for command line installs.

Macintosh MUI installers

Since there is no Acrobat Standard for Macintosh, there is a single MUI installer which behaves as follows:

  • All serial numbers are language independent.
  • All languages are installed by default.
  • The OS language will determine the language in which Acrobat will be launched.

The serial number is read by the application at launch time, and the OS locale controls which language the application should load. Trials are available in all supported languages, although only a single trial language can be installed at any point of time.

Machine-level details

The application language is selected during the installation of the initial major version using Setup.exe and is then stored on the system. For example, on Windows, it’s in:

[HKEY_CURRENT_USER\Software\Adobe\<product name>\<version>\Language]"UI"="ENU"

The product UI language is actually determined by the sidecar dll stored in:

[HKEY_CURRENT_USER\Software\Adobe\<product name>\<version>\Language]"current"

Therefore, if a user switches the dll under current or changes the UI key, the two keys may not match. Ultimately, the dll under current determines the product language.

Locale and language codes

Installer filenames include a locale identifier consisting of consists of a language code and a country code. For example, the Reader installer filename is in the form of AdbeRdr<version>_<language code>.exe. Thus, AdbeRdr10_en_US.exe is an English installer.

Note

Details about what languages are supported in each release appear in the Release Notes.

Installer components and workflows adhere to the ID system used by Microsoft. For details, see:

These IDs are also used on the command line, in installer tables, and elsewhere.

Windows XP configuration

Note

Products that support Windows XP have been discontinued.

On Windows XP machines, the OS’s regional settings may need to be changed to enable non-Latin language selection during a MUI install. Regional switching is not an Acrobat feature but how Windows XP works with codepages.

To change the OS settings:

  1. Control Panel > Regional and Language Options.

  2. Selected Advanced tab.

  3. In Language for non-Unicode programs, select the Language.

  4. For Japanese, Chinese, and Korean:

    1. Choose the Languages tab.
    2. Choose Install files for East Asian Languages.
    3. Reboot if you don’t immediately see these languages available under Language for non-Unicode programs.

Codepages

XP uses codepages to enable certain character support. Codepages are the way Windows enabled non-Latin language character encodings before Unicode was supported. For an overview, see http://en.wikipedia.org/wiki/Windows_code_page.

Selecting a codepage activates all the languages associated with that code page. For example, changing the regional settings and selecting a codepage for Czech also makes Polish, Hungarian, etc. available, but not Turkish.
