If you have any difficulty, get in contact with Wondershare technical support!
I bought the software, downloaded and it did not work the first time. I contacted Wondershare technical support and I received a new link to download a new version, which worked perfectly! It was a little bit stressful during the first time because after installing my WhatsApp several times in the iPhone and also in the Android, I had to wait for 24 hours to receive a new code form WhatsApp. At the end, I got my messages transfer and I now have my WhatsApp in my new IPhone! Thanks!!!
