View 1 RepliesJust today I've completed a trial version of my application - I then uploaded it to my webserver, and to my surprise a user already (almost one hour after I uploaded it) bypassed the protection and used the software 8 times (instead of the limit of 1 use)!
My "protection" was pretty weak. After the program has been used, it just writes a value to a single registry key. The user just deletes this registry key and can use the program once more, and so if someone does this enough times, he can use the software for as much time as needed.
Anyway, since I'm not really experienced in programming, do you guys have some nice working and possible easy to implement trial protection? I'm not looking for anything too serious, but it shouldn't be as easy to bypass as my current protection.
Ive created a trial application , but how do i stop that application from running again on the same ip address? Just so the user cant re-install it and use it again.
