At least in Pro, and most corporate environments.  User settings usually 
go in a subdirectory like:

C:\Documents and Settings\<user name>\Application Data\<software company 
name>\<application name>

Or sometimes, if the installer is set up for it:

C:\Documents and Settings\All Users\Application Data\<software company 
name>\<application name>

Note the "All Users" folder tends to be hidden.  Also, these paths can 
be changed in the registry, so you usually have to use the ShellAPI to 
get them.  Permissions on the former are supposed to always allow read 
and writes, according to the Windows guidelines, but you'll find 
sometimes an admin will lock them read only.

P.S. I've never used this in FPC, but run into it all the time in 
Delphi, especially in the more locked down corporate offices, the type 
where you have to have an IT guy scheduled a month in advance to get 
anything installed and then you have to tell them up front every single 
folder and registry key you'll need to read and write to.
