Inno Setup - Install file in user's profile

I'd imagine this has been answered before, but a few searches didn't yield anything. I need to install a file in the user's profile. Unfortunately Vista and XP have different paths for them. Is there an easy way to specify the destination directory should be the "profile", or do I have to determine if the OS is Vista or XP and then install to either c:\users\%profile% or c:\Documents and Settings\%profile%?

Let me know if I can explain anything better.

Thanks,
Brian


EDIT:
I guess I should explain this better. For example, if I'm using ISTool and use {%UserProfile} will it work with both XP and Vista?

Yes, with Inno Setup you need to create code in the [Code] Section to determine if you are running on Vista then chose one folder or default to the other. ********** does this with the Users folder and you could do this with any other folder that you want. Here is and example from ********** that you can use:

Code:

---

From Inno Script
[ Code]
function GetAppFolder(Param: String): String;
begin
  if InstallOnThisVersion('0,6', '0,0') = irInstall then
    Result := 'C:\Users\Public\' + ExpandConstant('{username}')
  else
    Result := ExpandConstant('{pf}');
end;

---

Yes, there are LOTS of examples of Pascal Script, but there is nothing I can find that shows how to call the function.

I've tried

#define OutputFolder {Code:FunctionName}
#define OutputFolder {Code:FunctionName()}
#define OutputFolder {FunctionName}
#define OutputFolder {FunctionName()}

The compiler doesn't accept any of them...

It just complains about the Opening Brace or "Code:" or "Undeclared identifier"
