free courses

Not really sure what you need. You can ‘sell’ free items, and manage memberships with https://www.woothemes.com/products/woocommerce-memberships/ but depends on your needs.

I would like to sell online courses. After payment free access to the course. I do not want the user to download the online course

What does the ‘course’ consist of though? Are they posts? External content? Something in person?

Lessons online SCORM type developed by an external program.
Ex. WordPress course. The user buys access to this course. Once you buy the system allows access for 30 days only for the course that you bought. This course can be an AVI file, PDF, SCORM, etc.

I was using Moodle, but it does not do e-commerce, need a bridge. I’m opting for a simpler thing, all in wordpress.

There are integrations I see: https://wisdmlabs.com/woocommerce-moodle-integration-solution/

Thank you, I already knew this integration

But I wanted everything in one program, wordpress.

In this integration, although complete, I do not use all moodle resources, and become lighter, thought of using woocommerce to control access and some other worpress plugin for online courses or only woocommerce.

Ok sounds like you need to research into LMS/course plugins first? WooCommerce won’t manage that aspect for you.

Thanks
