The languages below are currently supported by WiX (to see the status of other languages, visit the localization project page). Make sure you specify both the correct language and codepage codes in both your Product and Package tags; without the proper language settings, you might see error messages to pop up unexpectedly in a language different from the base language of your installer, and without the proper codepage, accented or non-Latin letters might not appear at all.

* We also offer alternative, cleaner, more fluent, easier-to-understand translations instead of some localization files in the released package. They differ in some places from the usual wording used by Microsoft in their installations but, in our personal opinion, they use simpler and better language. You are completely free to check them out and decide which one you want to use in your install packages.
Released languages are compiled into the WixUI extension library. To use them, simply provide the name of the culture. If you use the integrated environment, there is a Cultures field in the project properties dialog where you can specify the same. If you specify more than one culture identifier in a comma delimited list, a separate installer will be created for all of them.

Finished languages (those waiting their approval for release) or alternative language files (either downloaded from the table above or your own) can be specified directly on the command line. In the integrated environment all you need to do is to include the .wxl file among your source files, the appopriate installer will be created automatically.
