Disabling the CANCEl button on the Finish page

Hi. I'm doing a NSIS installer using MUI. But on my finish page the CANCEl button is enabled. I want it to be disabled, because it has no purpose there. How do I do that ?

	!insertmacro MUI_INSTALLOPTIONS_WRITE "ioSpecial.ini" "Settings" "CancelShow" "0"

read the modernUI help 😉

Thanks. It worked.
