When you copy a Windows Vista Service Pack 1 (SP1) Language Pack to a Windows distribution, you must use the versions of the source and license files that match the Windows image that you want to install. For example, for Windows Vista SP1 images, you must use the source and license files from a Windows Vista SP1 language pack. Do not use Windows Vista source and license files on a Windows Vista SP1 image. This use is not supported and might corrupt the image.

In the OEM Preinstallation Kit (OPK) User’s Guide and the Windows Automated Installation Kit (AIK) User’s Guide, the "Copy a Language Pack to the Windows Distribution" topic does not describe how to expand a Windows Vista SP1 version of an LP.cab file. You can use the following method to expand and to apply the source and license files for a Windows Vista SP1 image.

Important These instructions apply only for Windows Vista SP1. For Windows Vista and Windows Server 2008 images, use the instructions that are described in the user’s guide.

The following instructions must be run from an account that has administrator permissions.

1.	Copy your Windows distribution to a local directory. For example, copy the contents of the Windows installation DVD to a directory that is named C:\Windows_distribution.
2.	Create the Langpacks folder in the Windows distribution. For example, at a command prompt, type the following command: mkdir C:\Windows_distribution\Langpacks
3.	Copy the Windows Vista SP1 language pack (Lp.cab) and the parent folder, such as fr-FR or en-US, to the \Langpacks directory of your Windows distribution. For example, at a command prompt, type the following commands: • mkdir C:\Windows_distribution\Langpacks\Fr-fr • mkdir C:\Windows_distribution\Langpacks\De-de • xcopy C:\LPs\Fr-fr\Lp.cab C:\Windows_distribution\Langpacks\Fr-fr\Lp.cab • xcopy C:\LPs\De-de\Lp.cab C:\Windows_distribution\Langpacks\De-de\Lp.cab Note If you maintain different versions of expanded language pack files (For example, you maintain one version for Windows Vista and one version for Windows Vista SP1), you must keep these language packs in separate directories.
4.	Locate the Windows Vista SP1 Lp.cab file for the language for which you intend to add support, and then use the Expand.exe version that is included with the Windows OEM Preinstallation Kit (OPK) to expand the contents of the Windows Vista SP1 Lp.cab file to a local directory. For example, type the following commands at a command prompt: • expand.exe –f:* C:\LPs\Fr-fr\Lp.cab C:\LPs\Fr-fr\Expanded • expand.exe –f:* C:\LPs\De-de\Lp.cab C:\LPs\De-de\Expanded
5.	Copy the \sources and \license directories from the expanded language pack to the Windows distribution. Windows Vista SP1 language packs include an SP1 subdirectory. For example, type the following commands at a command prompt: • xcopy C:\LPs\Fr-fr\Expanded\sp1\sources\license\* C:\Windows_distribution\sources\license\ /cherkyi • xcopy C:\LPs\Fr-fr\Expanded\sp1\setup\sources\* C:\Windows_distribution\sources\setup /cherkyi • xcopy C:\LPs\De-de\Expanded\sp1\sources\license\* C:\Windows_distribution\sources\license\ /cherkyi • xcopy C:\LPs\De-de\Expanded\sp1\setup\sources\* C:\Windows_distribution\sources\setup /cherkyi
6.	Mount the Windows image in the Windows distribution. This is required for Intlcfg.exe to report the list of languages that are installed in the .wim file and to re-create the Lang.ini file. Use ImageX to mount the Windows image. For example, type the following command at the command prompt: imagex /mountrw C:\Windows_distribution\Sources\Install.wim 1 C:\Wim_mount
7.	Use the intlcfg -report option to report the languages that are available or installed to the Windows image. For example, type the following command at the command prompt: intlcfg.exe –report –dist:C:\Windows_distribution –image:C:\Wim_mount Verify that the correct languages are displayed as available languages.
8.	Re-create the Lang.ini file, and select the default international values to use. When you add or remove language packs from a Windows image, you must re-create the Lang.ini file. The Lang.ini file is used during Windows Setup. The Lang.ini file contains a list of all the language packs that are available, the locations of the language packs, and the default language to use during Windows Setup. For example, use the following command to re-create the Lang.ini file: Intlcfg.exe –genlangini –dist:C:\Windows_distribution –image:C:\Wim_mount
9.	Unmount the .wim file. For example, type the following command at the command prompt: imagex /unmount C:\Wim_mount
10.	Do one of the following to specify the default international language settings: • Use Intlcfg.exe to set the default languages and the locale settings. For more information, see "Configure International Settings with Intlcfg.exe" in the OPK User's Guide or in the Windows AIK User's Guide. • Use an answer file to specify the languages and the locale settings. For more information, see "Configure International Settings in an Answer File" in the OPK User's Guide or in the Windows AIK User's Guide.
