Distributing a runtime project?

I have developed a Runtime project during the course of my studies. It is an Interactive Documentary about an old computer CSIRAC. It is not a game and was developed for educational purposes.

I have managed to package the project into an installer. You can install Runtime, and all the content packages automatically.

Now that I have completed the project can I place this single file on the web for online distribution? There would be no fee, it is a non-commercial product.

Can I upload it onto a mirror site for distribution?

Or do I need to need to upload the content package files separately, link to where the user can download the engine, and instruct them on how to install everything?

Thanks

Oh Yeah,

I've got a site set up for it,

There's a trailer and stuff, but i don't have space to host the app yet. Once it's live you should be able to get it here.
