Question: I’d like to know how to script to download a second file which is a zip but initially give a choice between two zip files; download, unzip and delete the zip. The zip files each have different names but the contents have a different name to the zips (each the same name); no renaming required. This question is a little similar to Apply Download file condition in inno-setup
The files in question are downloaded via the SourceForge website. The programs (clones) these files are intended for are either not listed on SF or have changed purpose.
After fixing the PChar
bug: InnoTools Downloader not working with Inno 5.5 I'm now able to re-use this Inno Setup script from 2011 but want to expand it slightly but struggling to.
#include ReadReg(HKEY_LOCAL_MACHINE,'Software\Sherlock Software\InnoTools\Downloader','ScriptPath','');
[Code]
procedure InitializeWizard();
begin
itd_init;
{ Set download source.. }
itd_addfile('http://www.example.com/Textfile.txt', ExpandConstant('{tmp}\Textfile.txt'));
itd_setoption('UI_AllowContinue','1');
itd_setoption('UI_DetailedMode','1');
{ Start the download after the "Ready to install" screen is shown }
itd_downloadafter(wpReady);
end;
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep = ssInstall then { Lets install the downloaded files }
begin
FileCopy(ExpandConstant('{tmp}\Textfile.txt'), ExpandConstant('{userappdata}\program_name\Textfile.txt'), false);
end;
end;
Working code based on the answer:
#pragma include __INCLUDE__ + ";" + "c:\lib\InnoDownloadPlugin"

Only after posting my answer, I've noticed that despite you tagging the question inno-download-plugin, you are actually using InnoTools Downloader. Do not – InnoTools Downloader is dead and unmaintained.
Also note that the Inno Setup 6.1 has a built-in support for downloads. With that API, the solution will be easier, but different than what is shown below to IDP. See Inno Setup: Install file from Internet.
In the examples
folder of Inno Download Plugin installation, there are components1.iss
and components2.iss
examples.
The first shows how to use idpAddFileComp
to conditionally download a file, when a component is selected.
I'm re-posting a full example:
; Uncomment one of following lines, if you haven't checked "Add IDP include path to ISPPBuiltins.iss" option during IDP installation:
;#pragma include __INCLUDE__ + ";" + ReadReg(HKLM, "Software\Mitrich Software\Inno Download Plugin", "InstallDir")
;#pragma include __INCLUDE__ + ";" + "c:\lib\InnoDownloadPlugin"

idpAddFileComp('http://127.0.0.1/src.zip', ExpandConstant('{tmp}\src.zip'), 'src');
idpDownloadAfter(wpReady);
end;
Caveat: The component name passed to idpAddFileComp
must be in lowercase (the actual component name can use uppercase).
