Indy is not working anymore after update

Question

I had all kind of problems with Indy and following someone’s recommendations (at stackoverflow) I have updated to the latest version of Indy - at least this is what I intended to do.

Before starting the installation, I have manually deleted all files containing the "indy" word from my Delphi and from registry. Then I have followed the standard install procedure: http://www.indyproject.org/sockets/Docs/Indy10Installation.en.aspx

Now the piece of code below is not working anymore. The code just returns FALSE;

function Download(CONST aSourceURL: string; CONST aDestFileName: string; OUT aErrm: String): Boolean;
VAR
  Stream: TMemoryStream;
  IDAntiFreeze: TIDAntiFreeze;
  fIDHTTP : TIDHTTP;
begin
  fIDHTTP := TIDHTTP.Create(NIL);
//  fIDHTTP.ConnectTimeout:=5000;     <- not recognized
  fIDHTTP.ReadTimeout:= 1000;
  fIDHTTP.HandleRedirects := TRUE;
  fIDHTTP.AllowCookies := FALSE;
  fIDHTTP.Request.UserAgent := 'Mozilla/4.0';
  fIDHTTP.Request.Connection := 'Keep-Alive';
  fIDHTTP.Request.ProxyConnection := 'Keep-Alive';
  fIDHTTP.Request.CacheControl := 'no-cache';
  IDAntiFreeze := TIDAntiFreeze.Create(NIL);

  Stream := TMemoryStream.Create;
  TRY
    TRY
      fIDHTTP.Get(aSourceURL, Stream);
      {
      if FileExists(aDestFileName)
      then DeleteFile(PWideChar(aDestFileName)); }

      Stream.SaveToFile(aDestFileName);
      Result:= TRUE;
    EXCEPT
      On E: Exception do
        begin
          Result:= FALSE;
          aErrm := E.Message + ' (' + IntToStr(fIDHTTP.ResponseCode) + ')';
        end;
    END;
  FINALLY
    Stream.Free;
    IDAntiFreeze.Free;
    fIDHTTP.Free;
  END;
end;

There is any way to see which version of Indy I have installed?

Edit: ~~Also I get an "Unit idHTTP was compiled with a different version of IdException.IdException" message.~~ Fixed.

Sounds like you have a bad install, such as if you did not completely remove the older version before installing a newer one (just looking for files with "indy" in the name is not enough). — Remy Lebeau
The installation works now (indeed I had to clean Delphi folders really well and the registry also. However, the code still doesn't download the file. — External Server Error
What exactly is not working now? Are you getting errors? Bad file data? You need to be more specific. In any case, I would suggest you get rid of the TIdAntiFreeze and move the download into a separate worker thread. If you need Download() to be a blocking function, it can wait on the thread to finish its work. — Remy Lebeau

You should first use the Delphi setup to uninstall the version of Indy that is installed with Delphi - then you can cleanup any remaining file. You should not start by cleaning folders and registry by hand. Then you can install another version. Be aware some releases are "breaking"
