Hola,

Yo creo que la función que mencionas sí que puede retornar la ruta que necesitas. Si no me equivoco la constante sería "CSIDL_APPDATA".

Código Delphi [-]
 CSIDL_APPDATA = $001a;
 { Version 4.71. The file system directory that serves as a common
   repository for application-specific data. A typical path is C:\Documents
   and Settings\username\Application Data. This CSIDL is supported by the
   redistributable Shfolder.dll for systems that do not have the Microsoft
   Internet Explorer 4.0 integrated Shell installed. }
