Is it feasible/sensible to wrap an Inno Setup installer inside an MSI for easier distribution via AD?

Question

Our installer is written with Inno Setup and we are actually quite happy with it. Yet some customers keep asking for an MSI installer which they could more easily distribute

Answer 1

Doing so would be pretty much equivalent to delivering a ZIP file and calling unzip by the end of installation.

With such approach AD and Windows Installer would be fooled as if dealing with proper MSI installation, but as it is not the case, they'd backfire on you on the very first occasion.

Don't go this way.

And WiX is superior toolset to InnoSetup, anyway, so the time you'll spend on learning and porting will pay off by better support of collaboration.
