I have a pc that was purchased from Dell with Office 2010 on it. I paid extra for Office 2010. It is registered and working fine. A person that was doing charity work for a church has quit the job and has removed Publisher from her computer. She gave me the Publisher 2010 original dvd in the original package with the Product Key. I do not know the sequence of installation. I do have my Office 2010 product key also if needed. What is the procedure to install Publisher?
