another question, maybe not last. how to integrate INIFile function which changes player name in steam_emu.ini after install, to Language changing? For eg:
During installation i will check English language and after install installer will change "Language=spanish" string to "Language=english" in steam_emu.ini.

In this way, it will be more useful for users if we automate the script. I really loved this script.

For your first problem maybe this will work (If the installer has only one disk).

procedure CurPageChanged(CurPageID: integer);
var
  I: Integer;
  CompFile: String;
begin
  //...
  if CurPageID = wpWelcome then
  begin
    //....
    #if UseComponents == "1"
    if ComponentsPageAvai then
    begin
      for I := 0 to GetArrayLength(CompIndexList) - 1 do
      begin
        CompFile := GetIniString('ComponentsSettings', 'Component' + IntToStr(CompIndexList[I]) + '.File', '', ExpandConstant('{tmp}\Settings.ini'));
        if (ExtractFileExt(CompFile) <> '') and (not FileExists(ExpandConstant('{src}\' + CompFile))) then
        begin
          ComponentsList.Checked[CompIndexList[I]] := False;
          ComponentsList.ItemEnabled[CompIndexList[I]] := False;
        end;
      end;
    end;
    #endif
  end;
  //...
  //...
end;

To how to integrate INIFile function, ask kaktor to enter the function for this.
Or you can add the code copying from the CIU v3 (Custom Installer Ultimate) script here in the forum (just over 100 lines of code).
To adapt the code you only need change languages of the code and also the GetValStr for the Settings.ini.
