Your app is for desktop, tablet or phone?

Have you considered to use User settings for storing date of first launch and test this setting?

For Trial Period: You can store the installation date in the registry when your applications gets installed & checks every time when your application starts whether it completes the 365 days or not but it has some pitfalls. For more detail you can follow below links.

see when you install your application at that time enter the current date in registry. whenever user changes the date of system & launch your application at that time check the date from registry & changed date from user, if its mismatched then you know what to do. just show up the message to user that he messed with system date & close the application. this way you can manage trial period.
