Is there a way to sign code for free (or atleast not need to pay over £200 for it)? Im a student and cant really afford much but I have been working on a website and made an electron build for it, however downloading the installer prompts the user to discard it in chrome, then running the installer prompts the user to select do not run in the windows security thingy as its from another computer.

What would be the best way around this if I cant get a certificate for it?
