Please tell me how can i make my application setup as a trial verion for 30 or 15 days.

may be you should try Application Deployment page of the forum. Also PM Randem

Thanks for the suggestion.

Not much to it in theory.

You use an installation that is scripted or has a "post installation action" that generates a time-bomb date and stores it someplace (registry, a file). The program must be written to fetch that date and stop with a message if it has passed.

The tricky part involves making this stored date hard to find and falsify, as well as making it hard to locate the fetching/testing logic within the compiled program you install. There is no simple formula for doing this, and how tricky you need to get is really a tradeoff between the risk and the effort/cost.

For more serious situations you might look into commercial offerings. Generally you'll need to prevent sharing of install keys as well so you might need product registration, etc.

How can i get the date details (registry details) while building the setup file in inno setup wizard.
