I have Outlook 2003 on my desktop loaded from a recent legit copy that I bought and I wanted it on my laptop too so I can sync e-mails and tasks etc.
I just loaded it on to my Sony VAIO laptop running XP and all seemed to go well. However when I went to use it I was asked for the product key again even though it had asked me for it on the original load. I enetered it and was told it was incorrect. I tried again and still no good. So I uninstalled and started from scratch with excatly the same results. Product key accepted on loading then refused when trying to run the software.
