Hi all,
Problem solved, I finally got the serial number and when introduced was accepted.
According to what I understood I had unecesarily installed the "old" versions, because I thought that the upgrades should find them installed in my computer. What should I do now?, can I uninstall them? or should I have to unistall every thing. I don't like to have programmes using hard disk space unnecesarily.
Regards,
Jarc
