Something wrong with your update, the build should be "29.0.53982.0329" ...

A digital signature remains valid until it or the issuing certificate (chain trust) is revoked. When it expires in time, it is still considered valid. You cannot use a certificateto for signing purpose that has already expired, obviously. As for OSCP and CRL, in any case the possibility of invalidating a signature (or a certificate) must be guaranteed ... it is the basis of the concept of public signature. I don't know for how long it will still be possible to use "file" certificates like those of LET'S Encrypt for uses other than simple SSL ... the legislation (for example the Italian one) considers the digital signature valid ONLY and EXCLUSIVELY if produced by HARDWARE devices (specific), and it seems to me that the rest of the world follows this. So certificates with a validity of less than 1 year are not feasible if combined with classic USB TOKENS for example. Bye

A public signature is subject to revocation, which I can imagine would happen very quickly if a malware signature is verified. Also, the signature would be easily identifiable and the malware could therefore be blocked in virtually "zero time".

And all the features about 12.2 Release. The CE edition is like the 12.1.

Here will be all features for the various RAD Studio Editions (included CE): https://www.embarcadero.com/docs/rad-studio-feature-matrix.pdf

If you refer to this notice of CVE: https://github.com/madler/zlib/issues/868 they have resolved with 1.3.1 version. And the new Delphi version use the right version:

Sorry, but you are not right. For example no one can ACQUIRE data about HEALT status without your explicity WRITTEN and PREVIOUS consent. Thw European law is not only about how you threat the data, but also about you acquire the data ... So if one send you a screen shoot with name, age a healt status behind the scenes, you will be in fault if you don't have the explicity consent. This happened to a client of mine (for whom I made a piece of management software). It is not uncommon to find difficulties in sending information, that is, sending it and having a response, due to the GDPR.

I dont' know these components, but the error (you show incomplete message) seems to indicate that the scanner driver is not installed (or the scanner is offline). Again, I do not know the components nor have I ever developed a scanner application, and I could certainly be wrong.

I really don't know what to say ... I have no issues about this, and I debug to asm level too. But I really don't have any issues on debugging. And I'm using the offline installer too (I've always used it). Good luck.

You don't have the UPDATE version of RTL (I mean 12.0, 12.1, 12.2) with VERxxx. By now if you see a lot of packages like Indy, FastReport, Jvcl, etc ... they use near they same like you example, but there is not minor version (UPDATE) identity: you can see Delphi12 but not Delphi 12.2, all minor releases are indentified like Delphi12.

I explain BAD: the example I suggest is like @limelect do with JVCL -> VERSION IS FROM APP INFO, NOT FROM DELPHI VERSION. FOR Delphi version, like I told more times there is the "GetRTLVersion" function from System uniti: https://docwiki.embarcadero.com/Libraries/Athens/en/System.GetRTLVersion

It come from INFO from application setting. You can use also in this way (I use it since decades without JVCL) ( EDIT :THIS EXAMPLE REPORT INFO FROM APP INFO, NOT FROM DELPHI VERSION !!!) function GetAppVersion: string; var Size, Size2: DWord; Pt, Pt2: Pointer; begin Size := GetFileVersionInfoSize(PChar (ParamStr (0)), Size2); if Size > 0 then begin GetMem (Pt, Size); try GetFileVersionInfo (PChar (ParamStr (0)), 0, Size, Pt); VerQueryValue (Pt, '\', Pt2, Size2); with TVSFixedFileInfo (Pt2^) do begin Result:= 'Version: '+ IntToStr (HiWord (dwFileVersionMS)) + '.' + IntToStr (LoWord (dwFileVersionMS)) + '.' + IntToStr (HiWord (dwFileVersionLS)) + '.' + IntToStr (LoWord (dwFileVersionLS)); end; finally FreeMem (Pt); end; end else begin Result:= 'Version: NOT RECOGNIZED'; end; end; I think he wants to have the version of RAD STUDIO that build the exe file. The GetRTLVersion do this (to UPDATE level) and it is include in the System Unit.

Yes, you can use the GetRTLVersion function. That return the Major release and Minor release ... for example Athens12.2 -> is $2402 Only Update level version, no patch informations. It is a new function that works from Athens 12.

I think that file is part of commercial project, you must pay for it: https://www.eztwain.com/

I remeber somethings about decades ago ... may be the property is Sheet.Cells[x, y] or Sheets.Cells[x].Column ? For your facility, if you import the Excel typelib, you will able to see all properties of all "components" in the "Excel..._tlb.pas" created. These should be near the same as you use with OleObj.
