Are comments in Inno Setup [Code] section stored to a generated installer?

Anyone knows if the //Comments in the [Code] section of the .iss file are stored also in the compiled Setup.exe file or not?

In other words... if someone unpacks the Setup.exe file, can he retrieve the comments in some manner or absolutely not?

Solution

  • Comments are removed already by a preprocessor. So the comments do not even make it to the compiler (which would remove them too anyway), let alone to the binary.

    You can easily check that by calling SaveToFile at the end of your .iss script and checking the generated Preprocessed.iss file:

    #expr SaveToFile(AddBackslash(SourcePath) + "Preprocessed.iss")

    For example this:

    [Code]

function InitializeSetup(): Boolean;
begin
  { Secret comment }
  Result := True;
end;

#expr SaveToFile(AddBackslash(SourcePath) + "Preprocessed.iss")

    ... will be filtered to this by the preprocessor:

    [Code]
function InitializeSetup(): Boolean;
begin
  Result := True;
end;
