I am trying to move TMG8 to a new Laptop running Win8 from an older desktop machine running XP. I have copied the original tmgsetup.exe across and was able to install TMG8. However when I try to register the copied version I am getting the message "Registration data is invalid." I have used copy and paste to copy the registration data and serial number directly from the original email. I have tried uninstalling and reinstalling sevral times, both with the original tmg8setup.exe and the latest version as well with the same results. What am I doing wrong.
