Delphi signature in exe files

Question

type
  TDelphiSignature=record
    Signature:array [0..3] of LongWord;
    Version:string;
  end;

const
  DelphiSignature:array [0..2] of TDelphiSignature=(
    (Signature:($384F3D26,$B83782C2,$034224F3,$833A9B17);Version:'Delphi Entreprise'),
    (Signature:($235D7823,$19F3A5B6,$0240F343,$C711D126);Version:'Delphi Perso'),
    (Signature:($98DF8CA2,$793A3C7B,$093F7126,$17252A0F);Version:'Delphi Pro')
    // ...
  );

The above are version signatures found in Delphi compiled EXE files in the DVCLAL resource. I'm looking for other signatures, such as ones for Architect editions, and more importantly, for version numbers (6, 7, 8 ...) that are visible in the resource data.

The signature generated by RAD Studio 2010 Architect is the same one you have for Enterprise. The DVCLAL resource only tells you the particular Edition of Delphi/BCB used. Individual Delphi/BCB compiler version numbers are not stored or encoded anywhere in the compiled executable.

Update: I found this to be some useful information about the inner working of the DVCLAL resource:

Thanks - « Delphi/BCB compiler version numbers are not stored or encoded anywhere in the compiled executable » ... so there is no way to know the version. This is definitive? – volvox Jul 29 '10 at 00:45
Pretty much. About the only way to determine the particular version, AFAIK, is to manually analyze the DFM resources and PE import/export tables looking for version-specific VCL properties and functions. That is not going to be very reliable. – Remy Lebeau Jul 29 '10 at 22:53
Link seems to be dead. – LU RD Jan 09 '17 at 13:09
@LURD and sadly, it looks like the dvclal folder was never captured by the [Internet Archive](http://archive.org) (though the site itself has been). And I can't find any other site that documents the known signatures. – Remy Lebeau Jan 09 '17 at 16:18

That file disappeared, it re-appeared at https://assarbad.net/stuff/miscprogs.zip but cannot be archived in the WayBack machine or Archive.is, so I saved it via my blog at https://web.archive.org/web/20190107185701/https://wiert.files.wordpress.com/2020/11/miscprogs.zip Need to take a look at it later. – Jeroen Wiert Pluimers Jan 07 '19 at 18:57
