you might try specialfolderpath("0x0023") which is the common app data folder. (app data for all users).  I can't test on xp.  On vista/7 the directory is c:\ProgramData On xp it should be c:\Documents and Settings\All Users\ApplicationData

You'll probably want to create a subfolder for your app of course.
