The software is not working in order to obtain the necessary data on how to move it, therefore you have to do it the manual way.
Use a Flash drive and copy the installation folder, then paste it on the new PC in the same location. For license transfer, use the same way to activate it. Look in the installation folder for license files or check the built-in section to learn about the help files and various ways to activate it. Typically, the software should also have a section to deactivate it under the Help menu in the main menu bar. Use that first, transfer the software and backup the data, and reverse the procedure and eCopy Desktop should be functional again.
