How to get administrator group name in different languages

Question

I'm developing a installer using Inno Setup, and I need to create a windows user with administrator privileges, I can do it normaly using this command: net localgroup administrators USER /add

But there's a problem... if I execute this on a non-english Windows, the "administrators", group will not exists, aka: if installing on pt-br Windows it will be called "Administradores".

I was wondering if there's a windows variable wich store the admin group name.

Note that using Inno Setup i'm able to use vbs scripts.

Answer 1

I did a function to Inno Setup, also, I guess it will works for Delphi.

function GetNameBySID(const SID: string): string;
var
  WbemLocator, WbemServices, WbemService, WbemObjectSets: Variant;
begin;
  Result := '';
  WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
  WbemServices := WbemLocator.ConnectServer('localhost', 'root\CIMV2');
  WbemObjectSet := WbemServices.ExecQuery('SELECT Name FROM Win32_Group where SID="'+SID+'"');
  if not VarIsNull(WbemObjectSet) and (WbemObjectSet.Count > 0) then
  begin        
    WbemObject := WbemObjectSet.ItemIndex(0);
    if not VarIsNull(WbemObject) then
      Result := WbemObject.Name;      
  end;
end;
