When installing on a new computer, just refer to the most recent registration/download email that you received.  Follow the instructions in that email to download the most recent version and install on the new computer using those instructions.  Once installed, you can also transfer your old setups and saved jobs.  Use "Utilities", "Migrate/Copy Qimage Application Data" from the menu.  Using that option, you can copy all the saved information from one location to another (to a temporary disk and then to the new computer, through the network to the new computer, etc.).  If you'd like to do the data move operation manually, you can use "Utilities", "Explore Qimage Application Data" and that will take you to the location of the Qimage data files.  Simply copy all files/folders from that location to the same location on the new computer and you're ready to go.
