How to fix this error in SharePoint:
"The list cannot be displayed in Datasheet view. A datasheet component compatible with Windows SharePoint Services is not installed, your browser does not support ActiveX controls, or support for ActiveX controls
It started to days ago, for apparently no reason. ActiveX is enabled on this site and I had everything working fine so far. Not sure what went wrong.
... from IE check out your Internet Options, and look under 'Programs'->'Manage Add-Ons'
When I had this problem it was because an add-on was missing or disabled... * thinks * "Microsoft Office List 12.0" or something.
