Since Total Video Converter is a shareware application, you have the possibility to download only the trial/demo version that has nag screens and limitations. To unlock the full product, a user needs to buy the application from its official website and then use that registration code to activate the program. Access the program's website, click on Buy now and then follow the procedure. At the end of the buying process (if everything is well) you should receive an email with the registration code. Use that code to unlock the application.
