Solution 1

There are different ways to achieve this

1) encrypted license files that contains the expiry dates etc.
2) encrypted license keys held in the registry
3) challenge/response mechanism which require an internet connection
4) probably others.......

Try: License Key Generation[^] or: How can I create a Product Key for my C# App[^] or: c# Licensing[^]

Also, Cryptography 101 for the .NET Framework[^]

But I want my application should isatall only on one machine.
client could not replicate this instalation on another machine

Have option 3. Some kind of webservice at your end. Client would send the machine id with license and you activate it on your side. This way, client cannot use same license on other system.
