An older version of the MS Office Add-in needs to be uninstalled?

[Anonymous]

While configuring the AutoCAD Civil 3D 2011 installaton before installing AutoCAD Civil 3D 2011 on my Windows 7 64 bit PC for the first time, I receive the following message "an older version of the MS Office Add-In is currently installed.  Please uninstall the older version before installing the new version".  MS Office Add-In is not listed in my list of installed programs.  How do I go about uninstalling this item?

Thanks in advance for your time and consideration.

ps I am installing Civil 3D 2011 on top of Civil 3D 2010.  Should I remove Civil 3D 2010 first?

i know why that error is coming up your trying to install vault 2011 with civil 3d 2011

Do you have a “Client” entry for vault listed?  If a client entry exists, can you try these steps?
1.)   Control Panel > Programs and Features

2.)   Click Autodesk Vault Client

3.)   Click “Uninstall/Change”

4.)   Click “Add/Remove Features

5.)   Uncheck the “MS Office Add-in”

6.)   Click “Next” and follow the prompts to uninstall.
