After downloading the software on the computer, you can get the trial version which allows you to experience the operation of certain functions like transfer photos, music, videos, contacts, and messages in a certain amount. If you want to use these functions: Contacts Backup and Restore, Ringtone Maker, HEIC Converter, or transfer all the files without limitation, you will need to buy the registered version.
Win Version: http://www.fonepaw.com/downloads/dotrans.exe
If you have bought the program, you will receive the registration code through email. Then, what you should do is to register the function.
1. The single-user license only can work for your computer.
2. If you haven't received the license code, please check the trash bin in your email.
First, if you are using the free trial version, you will see the window automatically pops out every time you launch the program.
Or, you can click the Menu icon in the upper right corner > Register...
Then click the "Register" button and you will see the activation prompt. Enter the email that you used to purchase the software and the license key.
At last, click "Activate" to finish the registration and there would come a new webpage to tell you "Registration Succeed!"
