Localization of Windows Installer default strings in WiX

I am trying to localize a Wix installation. It is very simple, no custom dialogs or strings. Only using WixUI_InstallDir-dialogs.

I thought setting Product/@Language=1044 and Package/@Language=1044 would have the installer talk Norwegian.

Partly.

The dialogs are in English, but status update while the progress-bar moves are in Norwegian.

I have tried following the guide http://www.tramontana.co.hu/wix/lesson8.php#8.9

However, all the "default" strings b开发者_StackOverflow中文版uilt into Windows installer, do I need to translate those?

Or is there some localization-file available somewhere on the web I should download?

The dialog strings must be localized. WiX comes with 40 sets of loc strings; you specify them using the -cultures switch to Light.exe or the Cultures property in a .wixproj.
