Hello and welcome to Advanced Installer forums,
Thank you for your interest in Advanced Installer.
Indeed, this seems to be an Advanced Installer limitation. A fix will be available in a future version of Advanced Installer, thank you for bringing it to our attention.
Until then you can manually edit the .AIP(project file). In order to achieve that you can open the .AIP with a text editor(e.g. Notepad) and search the related site and in the
SecureBindings attribute you can write the hostname.
E.g.
where localhost is your hostname
When you will reload the .AIP project you should see the hostname.
Please let us know if that helped.
Best regards,
Dan
