Try this,

Its bit logical which i tried few months back as like this to one of my windows project. When the application (exe) getting installed into the client system save the date into the regedit (registry) with unique name. Every day (date) needs to compare with regedit date.

Note : User may change system date. so in regedit store two columns like installed date and future expired date. So here you need to check all those three dates. (installed date, future expired date, today date). Maintain flag inthe regedit, it will help to continue after you given key to that software. i hope you got better explain here.
