You need to specify the multi language option in your .pkg file.
For further detail please read the Series 60 SDK help
Symbian OS v6.1 Edition for C++ >> Tools and Utilities >> Installation Reference >>Package File Format.pkg
There is also an SDK example (called "Language" !) that covers some of the issues, but it does not deal with AIF files.
