I don't know where you got your Microsoft Office Publisher 2010 from but I think if you check carefully you might find that it is not genuine.
if you bought Microsoft Office online from a genuine authorized microsoft retailer then you would have received the product key with the software. there are some websites online which claim that you can download Microsoft Office Publisher 2010 from them but as far as i know there is nowehere on the internet where you can download a genuine copy of any Microsoft Office software except the official Microsoft website.
the only Microsoft Office product you can download is the trial version of Microsoft Office 2010. trial versions of Microsoft Office are free to download but can only be used for the limited trial period. after the trial period ends you have to upgrade to the full version and pay Microsoft for an online activation code which unlocks the trial version's time limitation and allows you to use it indefinitely.
if you need this type of software but do not want to or cannot afford to pay what Microsoft Office costs, then you can use completely free software like OpenOffice, which is very similar to Microsoft Office and can even be used to open most Microsoft Office documents. you don't have to pay anything at all to download OpenOffice.
the website for Microsoft Office trial and activation code downloads is - www.microsoft.com
the website for OpenOffice is - www.openoffice.org
