Please be advised that TouchCopy 16 is required to access data such as Messages or Contacts for devices updated to iOS 10. If you previously purchased TouchCopy 12, you can upgrade to TouchCopy 16.
If you followed the steps above and your messages are still not displayed or TouchCopy indicates that your iPhone contains no messages, contacts or calendars, it is possible that TouchCopy is attempting to read a corrupted backup of your iPhone data. The solution of this is to delete any iTunes backups made of your device and then try again.
Firstly, remove your old iTunes backups...
Then, create a fresh backup in iTunes
Finally, if you are using a Windows computer, it may be beneficial to run TouchCopy as administrator, ensuring it has the correct permissions to access your backup.
To do this, make sure TouchCopy is closed. Then, right click on the TouchCopy icon either on your desktop or in your programs folder. Select 'Properties' and then go to the 'Compatibility' tab. On here please select to 'Run this program as an administrator'. Once done press 'Apply' and then 'OK'. Please then re-launch TouchCopy and try again.
