How to prevent unknown publisher popup when running Inno Setup installer on another computer?

Question

I've created an exe and compiled it with Inno Setup Compiler (v6.0.5). I've set AppPublisher to "MyCompany Ltd". But whenever I run it on a different computer to the one I created it on, a popup appears asking me if I want to run this program "from an unknown publisher". Moreover, when I added it to Start-up on both computers, neither show the publisher on the Start-up tab of Task Manager.

So, how do I properly specify the publisher? And if I do, will this prevent the popup coming up? As I want it to run on Start-up, having a nice big popup every time I boot up my computer isn't really that great.

Any help appreciated! Thanks in advance.

Answer 1

The "publisher" is not related to the AppPublisher directive.

The "publisher" is the subject of the code signing certificate used to sign the installer. You probably have not signed the installer. It's necessary these days. See InnoSetup - Code Signing Certificate.

Note that these days you need EV certificate. See security.stackexchange.com/q/222140/43677 – Aposiopesis
