how can i make setup of my project with trial version

[Ravi_21]

can anyone help me give suggestion in making setup with trial version

Take a copy of the existing code, and remove/limit some of the features. Have the installer automatically install the parts that are the same, then ask for a serial number. If none is provided, install the trial version of the rest, otherwise install the full version. To stop this from being bypassed, have the full version check a license file. (do not make the trial do this, as a faked file may unlock some things). A good license file would be a mac address, full name, organisation and time and date of install, all md5'ed with a key that only you (and your program) knows.

Alternatively, allow the user a time limit to which they use the application for. You'll have to implement some hack-proof techniques though, because the most obvious hack would be to turn back your computer time.
