Introduction
Does anyone receive the following error when you try to enable "Datasheet View" under any List?
=========================================================================
The list cannot be displayed in Datasheet view for one or more of the following reasons:
A datasheet component compatible with Microsoft SharePoint Foundation is not installed.
Your Web browser does not support ActiveX controls.
A component is not properly configured for 32-bit or 64-bit support.
=========================================================================
Reason
It happens if you install 64-bit Office 2010 on the Server. Why?
A 64-bit version of the Datasheet component is not available for Office 2010.
Solution
You can install the 2007 Office System Driver: Data Connectivity Components to enable the Datasheet component. It will work with the 64-bit version of Office 2010 as long as you are using a 32-bit version of an Internet browser.
