Answer 1

Inno Download Plugin by Mitrich Software.

• It's an InnoSetup script and DLL, which allows you to download files as part of your installation.
• It supports FTP, HTTP and HTTPS.
• It's kind of a drop-in replacement for InnoTools Downloader. Only few changes required.
• It brings a decent download display and HTTPS and Mirror(s) support.
