Material Science Engineering 9th. You could probably come up with a system that requires an internet connection, but without something that the user can't tamper with, I don't see a solution. Any solutions that rely on an untrusted element (an element of the protection that is under the user's control) is critically weak. The simplest way I can think of to protect against the user moving the clock back is to limit the total number of launches.

However, attempts to limit the number of launches requires persistence -- saving data to the disk, perhaps encrypting and storing a modified version of your activation data file - Imagine that you count one of the 30 days as 'used up' once the app has been launched, on a unique occasion, even when the same date is re-used. In order to avoid using up more than 1 'activation time day' when launched, the user must allow your software to re-save its activation file each time it runs. To block that approach, the user needs only to keep the apparent date from changing, plus they must either prevent you from storing anything to disk; or they can simply track and record your changes and reverse them out, either using a monitoring process, or using VMWare snapshots. About VMWare snapshots, you can do nothing. The virtual machine's disk is not under your control.

You can protect your app of users setting the clock back simply by storing in the registry the date of last execution. Each time the app is started you need to do the following: • Check current date (as reported by the system clock) against the stored last execution date and, if current date is earlier than the last execution one, consider that the trial period has expired (or whatever you prefer). • If the previous check is ok, save the current date in the registry and continue execution.

As WarrenP says, any technique storing information locally can be easily circumvented using VMware snapshots. And anyone, including those who check via internet, can be skipped via assembler level hacking.

Here's a discussion on Shareware trial enforcement with Delphi: Along with discussions on various 3rd-party solutions, techniques for DIY, etc. IMO, DIY is feasible if your app produces data that the user will want to keep around, then you can simply embed a copy of the usage/day counter in the database in such a way that they can't wipe it without destroying their data. I also like watermarking (printing 'trial' on reports, etc.), escalating nag severity, but I do not recommend or condone 'drop-dead' crippling until WAY past the expiration data.

I also like to measure 'days of actual use', instead of using a calendar. Registry manipulation works, and many of the 3rd-party protectors use it. But you need to be stealthy, and keep backups in several locations simultaneously. You should also consider having separate trial and registered versions. But also consider that pirates will buy the registered version with a stolen card, and put it on Rapidshare, BitTorrent, etc. Also note that elaborate defenses lead to support headaches. Sometimes PCs crash and the clock gets set backwards.

They install new harware. PCs get rebuilt, restored from backup, etc. If a user is running a debugger, he may be a software developer, not a pirate. If your app looks like it has been patched, it may be an overly-aggressive antivirus. And at any time, a shoddy patch for Windows may cause your program to think that it's being attacked, hacked, or reverse-engineered. You have been warned.
