Housing the course

Hello,

I have finished a course and the client would like it to be published somewhere besides an LMS for easy access. I am not sure how to go about this since this is new to me. The course is mostly for a senior audience so distributing the ZIP file to the individuals and providing instructions will be too complicated. Is there an easy way for the audience to access the course without an LMS? As much as I would like to use Review 360, it would not be reliable since the Articulate 360 subscription can run out at any time. 

Any ideas on how to publish the course for easy access are appreciated!
