Unpack SFX file using Inno Setup

Question

I'm trying to run Inno Setup to automatically extract my SFX file without having to run extract manually. Is there any way? I leave my script below.

Is there also a way to make Inno Setup extract the SFX in the Myprogramfolder created by the installer?

I have compressed the SFX file using Winrar.

Have you had a look at the answer to this question? It sounds like it might help you. https://stackoverflow.com/questions/34923104/how-to-create-an-installer-using-inno-setup-which-extracts-the-contents-of-a-ra — Andrew Truckle, Jan 06 '21 at 23:32
What does your script have to do with your question? Is the `Evilpack.exe` the SFX? Can you extract the SFX manually from commandline? What arguments do you use for that? — Martin Prikryl, Jan 07 '21 at 07:44
I looked at the article but it didn't work, thanks a lot Andrew anyway :-) — EnmanuelGo, Feb 22 '21 at 01:55
I wanted Inno to unpack the Evilpack.exe SFX files, thanks for Martin Prikryl — EnmanuelGo, Feb 22 '21 at 01:57

Is very easy unpack in silent way SFX, setup to silent from the menu option ADVANCED, then SFX options in winrar. That is all!!

Finally

[Files]
Source: "C:\pathtofile\yoursfx.exe"; DestDir: "C:\Program Files\";Flags: ignoreversion
[Run]
Filename: "C:\Program Files\yoursfx.exe";  StatusMsg: "Your MSG"; Flags:  runascurrentuser


 [Code]
 procedure CurStepChanged(CurStep: TSetupStep);
 begin
 if CurStep = ssDone  then
  begin;

  DeleteFile(ExpandConstant('C:\Program Files\yoursfx.exe'));

   begin
  // user clicked Yes
  end;
  end;
  end;

Instead of `DeleteFile`, just extract the `yoursfx.exe` to `{tmp}` and run it from there. The Inno Setup will take care of deleting the file. And you can delete your whole `[Code]` section. + You have the path in `[Run]` wrong. It should match the `DestDir`, not `Source`. – Martin Prikryl Jan 05 '22 at 07:01
