Do I need to keep the DVD in to use Toon Boom

So I just got Toon Boom, and I’ve used it before. But I bought it on a DVD. So I’d like to know If I have too keep the DVD in the player while using the program, or is there a way to keep it in my hard drive, or unless it’s done that itself?

Once the application is installed on my system and the license, I was able to run without any DVD.

Depending on the operating system it is generally a simple matter of clicking on an installer file and following the directions.
