Office 2010 Shared Features

Hi,

Recently I installed Microsoft Office Professional Plus 2010 (64BIT).  Now, I am trying to install PowerPivot for Excel 2010 (64BIT).  The setup will not completed because Office Shared Features is not installed.

I referred back to my software.  Selected Add or Remove Features.  Selected to Run all from My Computer.  Configuration completed.  I tried to install PowerPoint again and received the same error message.

Can I download Office Shared Features?  How can I verify if Office Shared Features are installed on my machine.

Thanks in advance for your assistance
