To get rid of the 'register with Adobe' screen at first startup:
Install Premiere Elements on a PC, start up the program and answer the 'register' screen. Then copy the file C:\Program Files\Common Files\Adobe\Adobe PCD\cache\cache.db
Deploy this file at the end of the Premiere Elements deployment job and the 'register' screen is history.
To prevent the country selection popup create text file "documents and settings\all users\application data\adobe\premiere elements\4.0\country.txt" and populate it with your country code. example: "244" for US
Or just copy the file from another installation.
