For all OpenEdge Developers Kits editions that require a subscription (not Classroom Edition) each developer must choose the versions, platforms and products that they wish to utilize within their own software kit. To see the earlier, supported versions of OpenEdge and within each OpenEdge Developers Kit edition see the Product Availability Guide.
There are pages on the customer support web portal to enter those choices and generate their own set of license keys, provided they have entitlement based upon the edition to which they have subscribed.
Each developer must have a ProgressID registered with Progress and that ProgressID is associated with a subscription plan. The developers can then download the appropriate media files from the Electronic Software Download (ESD) center and install the software kit on as many machines and for as many developers as their OEDK subscription covers.
