=====Modifier un fichier après installation=====
Utilité : modifier un pattern pour le remplacer, par exemple, par le dossier final d'installation.

Ajouter après chaque fichier une directive ''AfterInstall''.

''Source: %%"C:\fichier.txt"; DestDir: "{app}"%%; Flags: ignoreversion; AfterInstall: FileReplaceString('fichier.txt')
''

Puis, dans une section ''[Code]'' (à créer si inexistante) :
<code pascal>
procedure FileReplaceString(const FileName: string);
va
  MyFile : TStrings;
  MyText : string;
begin
  MyFile := TStringList.Create;

  try
    MyFile.LoadFromFile(ExpandConstant('{app}') + '\' + FileName);
    MyText := MyFile.Text;

    StringChangeEx(MyText, 'C:\BlaBla\', ExpandConstant('{app}') + '\', True);

    MyFile.Text := MyText;
    MyFile.SaveToFile(ExpandConstant('{app}') + '\' + FileName);
  finally
    MyFile.Free;
  end;
end;
</code>

=====Modification de la base de registre=====
Ici, pour lancer le programme en mode administrateur.
<code>
[Registry]
; Pour forcer l'exécution en mode administrateur
Root: HKLM; Subkey: "Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers"; ValueType: string; ValueName: "{app}\prog.exe"; ValueData: "RUNASADMIN"
</code>

=====Création d'un raccourci=====

Exemple d'utilisation :
  AfterInstall: CreateShortCut('runner.exe', ExpandConstant('{app}\file.exe'), 'Raccourci')
