Hi,
Does anyone have any advice on how to go about putting in time limits to a
program to give, say, a 30-day trial? And perhaps even more importantly,
how to implement a key system to remove the trial restrictions for
purchasers?
I highly recommend that you do not time bomb your software if you want people to use it and pay you for it.
Instead think addiction. Give them a product for free that does something useful. Let them have that functionality forever. Get them addicted to your software. Then, make sure the hook gets them to pay. For example, if it is server software, pause after some long period random number of days (30 to 60), at say 3am, and halt operation until they answer a math quiz. Let them keep using it but remind them to pay. Or if the software has some form of data entry, let them enter and use it with 100 records but if they want that 101th record, they need to pay. If they've entered 100 records, they are hooked. Or if the software manipulates data, manipulate the data so that they can see that it really does manipulate the data, and perhaps do it for files that are small with no restrictions, but for files that are large, mark them in some way so it is obvious that it can do the work, but they cannot use the results professionally. Think addition. Let them keep it and use it forever and make your hook be something that tips them over the edge.
If you time bomb it, or do a phone home, you'll eliminate potential customers before they get hooked and they will remove it from their hard drive before they can pass it to a friend.
Just my two cents.
