Where and how should I save license related information?

I have an application (C#) and I am tasked with putting some simple licensing scheme in it. While doing that I need to save that information somewhere in computer to limit the usage.

I need to save a date and a counter.

How and where I should save the information which, on Windows Vista, doesnt require administrative privileges to run? (Which means saving it in System32, Program Files, HKEY_LOCAL_MACHINE is not an option.)

Please do not flood the answers with "don't do it" or "it will be cracked anyway". I do understand those logics. I just need to do anything best that can be done for this purpose.

Solution

  • Consider using a third-party licensing component, such as XHEO - there's no need to reinvent the wheel.

    If you are still required to write your own license system, consider using the user's profile directories or the HKEY_CURRENT_USER branch.
