Before installing the program on the new computer I would recommend making a back up copy from the old computer and saving it to a memory device. To do this select "File" in the upper left and then "Backup - custom". This will allow you to choose where you would like to save the backup copy.
Then use the link below to download the Desktop version on the new computer. Once you install the program select the File menu and then Restore from Backup. This will import your patient data along with the registration code. A link to a tutorial video is below.
After you have verified your patient data has been successfully imported to the new computer, uninstall the Desktop program form the old computer to prevent any registration code conflict.
