I came across another bug with the multilingual package option:
When I create a multilingual package (default language: english (USA), additional language: german) and run the installer in the primary language (english) the manufacturer is set correctly in the windows Programs Panel (where you can uninstall the package). If, however, I use the additional language to install the product (german), the manufacturer is set to "Property.Manufacturer" instead of the correct value in the windows Programs Panel.
Is this a bug or is there a solution to the problem (besides not using a multilingual package)?
