Has anyone out there tackled the problem of integrating copy protection into a finished Windev application designed for a commercial market? What methods work and would be relatively easy to administer? I would also like to limit upgrades to those with up-to-date maintenance agreements. I'm thinking of distribution by Internet, shipping CD's or both.
Please don't suggest dongles. |

Please don't suggest dongles.
A simple and cheap way is to encrypt a rather short name/address text and a serial# and to show name / address on most windows and all the critical printouts. This will not support any licensing of a certain number of workstations and it will not protect against people willfully working with that (annoying) name on the main menu which isn't theirs.
All 'better' protections will employ dongles. Do not use Aladdin dongles, because there are dongle-replacements for that dongle available on the web. Always use an encoded license# which has to be stored in the dongle. Let your program encode the customer-input license and let it check against the dongle contents. Never ever just check for 'dongle present'. Means: Stay away from cheap dongles without memory. WIBU-key works and there are no cracks available.
Don't bind your software to the hardware (MAC address of LAN-card, Serial# of hard disk). Seems easy but you will definitely experience a situation where a) the customer is angry because their computer went bad and they couldn't get a new license# fast enough and b) you probably will never know whether they just told you that one of their computers has been defective or not. So, using that idea, they could get several license numbers while paying for only one.

| hello, I have succesfully integrated a product called "Crypkey SDK" with my Windev application. No dongle is required. I can license single (standalone applications) and network applications. I can even have the network program reside on each node for speed and limit the number of active concurrent licenses with the license located on the server. Server license will limit runs to the license count and hold additional users in a cue on a first come first serve basis. |
