serial numbers on standalones

[Björnke von Gierke]

I think it should also be possible to alter an existing custom property in a standalone, as long as the replacement text is the same length in bytes as the one you replace. This is because there's no redundancy caching in the stack file format. Better ask RunRev support if that's still true before investing any time into an approach like that tho.

So what you'd do is:

Make standalone with a custom property that contains dummy string, for example 16 chars long. Now use a stack, script or other means to find that dummy string in the standalone, and replace it with a "proper" license string that is also 16 chars long. Finally, your code in the standalone checks for the license string cprop, whenever the user enters his credentials. The standalone is now custom-coded for your customer, and no second one exists. Pretty easy to workaround for anyone snooping around, but so are most DRM measures.. Just think of Sim City 2013 ;-)
