How to localize status bar messages.

Hi,
When the MSI installer is running, there is a status bar.
Message appear above the status bar like:
Validating install
Copying new files
Registering product
Updating component registration
Creating shortcuts
Registering product

These messages that appear above the status bar are in the language files:
$(var.MSIFactoryFolder)\UI\Default\Language_jp-jp.lang

So I translate the English messages in Language_jp-jp.lang, and rebuild as Japanese.
But the status messages are still in English.
All other text appears in Japanese.
What else do I need to do?

So I then tried this: I then found the Progress dialog ProgressDlg.
There is an ActionText control above the status bar.
I clicked Translate and added my own ID named
PROGRESS_BAR_ACTION_TEXT.
Then I rebuilt.
Still, the status text appears in English.

Any idea what I am doing wrong?
Thanks,
Dave
