How do you set up......

Downloadable goods. For the life of me I cannot figure it out. Help Desk said go to the update products page on the backend, but I can not find it. Can someone please explain this in detail. I cannot find any info on this subject in any other posts.

have you read the manual? the ‘back end’ is the admin section, which is just to add a /admin.php to whatever adress your shop is at.
