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.

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?
