Help Me. I am waiting for ur valuable response From http://www.developmentnow.com/g/26_2004_10_8_0_0/dotnet-framework-setup.ht Hello Sandeep, You can use the registry to store the time of installation 1. Your installer should make a registry entry when it is installed. This entry should be encrypted so that external modifications are not permitted easily. 2. Your application should query this registry key on start-up, And use the DateTimeclass to see the time difference between the installation time and the current time. If it is beyond the trial time, the application should refuse to start-up or better still, prompt for a license key.
