JavaScript is switched off

Executive Suite is a game, so it needs scripts to run. The viewer you have opened this file in blocks them — on an iPhone that is usually the built‑in preview in the Files app or a mail attachment, which never runs JavaScript.

On a Mac or PC: double‑click the file. It opens in your normal browser and plays immediately.

On an iPhone or iPad: Safari, Chrome and Edge are all blocked from opening local files, so you need an app that renders HTML itself — either a dedicated offline HTML viewer, or a local‑server app that lets you open the file over localhost in Safari.

Nothing is broken and nothing is missing — the whole game is inside this one file.
