I am trying to use PowerPoint 2010 with a slide library. When I click Upload > Publish Slides within the slide library, I get the error "This feature requires Microsoft Office PowerPoint 2007. Either the application is not installed, or your browser is not configured to support ActiveX controls." I have Office Professional Plus 2010 - is it really not compatible?? I tried temporarily enabling all the ActiveX settings to no avail. It works if I install Office Pro Plus 2007, but the users have 2010. I am able to publish from PowerPoint to SharePoint (Save & Send > Publish Slides) using the library URL, and I can also drag and drop files using Windows Explorer, but ideally we would like the Upload > Publish Slides feature to work from within the library. Any feedback is appreciated, thanks!
We were having some trouble with Office (Excel, Word, etc) integration too and narrowed it down the the 64-bit version of IE9. The ActiveX controls used for Office integration are not fully supported for the 64-bit versions of IE. Are you using 32-bit or 64-bit versions of your browser?
The arcticle below says that Microsoft Office 2010 does not provide a 64-bit version of the Slide library and PowerPoint 2010 integration control.
