Windows Vista Ultimate language pack release information

Windows Vista language packs let you to take advantage of the Multilingual User Interface (MUI) feature of Windows Vista Ultimate. A Windows Vista language pack is a set of language-specific resource files that can be added to any language version of Windows Vista Ultimate.

When you install the Windows Vista language packs, the MUI lets you change the interface language of the operating system to any of the installed languages. This feature lets users select a language that they can use.



The MUI also lets you select different languages so that users can share the same computer. For example, one user may want to see the Windows Vista menus and other text in Japanese. Another user who logs on to the same Windows Vista computer may want to see the corresponding text in French.

Known issues during installation

Issue 1: You receive error code 1 or error code 2

Occasionally, language pack installation fails, and you receive error code 1 or error code 2. This behavior typically occurs for one of these reasons:

• Windows Update installed another update that requested a restart.
• A previous Windows Update process failed and put the computer in a corrupted state.

If you experience this issue, use the following methods.

Method 1: Install the updated lpksetup.exe package

Note This method only applies to error code 2. If you received error code 1, skip this method, and try Method 2.

Method 2: Restart the computer, and install only one language pack

Restart the computer, and then reinstall the language pack without selecting any other updates.

We recommend that you only install one language pack at a time because of the required download size and the installation time.

Issue 2: Language packs take longer than expected to install

Because language packs contain language-specific resources for all the Windows Vista components, the language packs are large and may take some time to install. The average download size is approximately 200 megabytes (MB) and may require up to 1,100 MB of free disk space to install. The installation process takes approximately 30 minutes. However, the time varies, depending on the performance of the computer.
