We have been commissioned to analyse an existing Delphi software and make any necessary bug fixes. The software is supposedly written in Delphi 7, so I installed it at short notice and loaded the project. Problem #1: The property "DoubleBuffered" is not found. As far as I remember, this did not exist in Delphi-7. Problem #2: The following units are used, among others Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.Buttons, unit6, unit12, Vcl.Mask, Vcl.ExtCtrls, shellapi, unit0, unit_Sicherheit, archiv_unit, Unit_GobaleFunktionen,Unit_Internet_Konfi, ExtCtrls, StdCtrls, Mask, Buttons, Controls, Classes; Questions: 1. which Delphi version should I at least install / purchase to read the above code? 2. how do I find out whether I need a normal or an Architect/Enterprise version?

Hi, thanks for the fast response. The last edit was around 2017, so I assume Delphi 10.x would be suitable. In the meantime I had a chance to look at the .csproj files. These files contain the productversion and that says, it's 18.2, hence Delphi 10.1

Oops, Sherlock. Sorry. Fixed.
