When I try to put my "upgraded 2007 to 2010" list in "Datasheet View" I get an error:
This 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.
The first one, I would think, is out because I installed SharePoint 2010 Enterprise. The second one is out because it worked for my old site and I have the site under my "Local Internet" security allowing all. The third one seems unlikely because the old site was 64-bit also.
