Recently upgraded from Office 2007 to 2010. Some days after install started to receive a message 'you need to activate this product' every time I opened an Office application. My IT guys did the ncessary to activate Office 2010, but since then my site selection (tab) button on any Sharepoint page will not open the drop-down menu and I cannot change the view of any document library to 'Explorer View'. I've been looking in forums and other sources and can see this is a known issue with IE8, but when it happened to me, I was using IE7. The only trigger I can see is the activation of Office 2010 Anyone had similar experience and anyone aware of a fix?

Could client integration features be missing from your permission set? Site selection tab? This sounds like Publishing site. It could be a permissions issue. Can you try or get them to try with a user with Full Control (site owner) and see if that makes a difference. Brian Bedard, MCTS - pioneeringsharepoint.blogspot.com - Twitter:@tigertoy

Looking at the date that Buntz posted this, I'm not entirely convinced he'll come back for his answers, but on the off-chance I would also suggest checking that Office 2010 Web Components are checked for installation, which I believe will sort out the mentioned issue.http://www.final-exodus.net

Thanks to you both for your contribution. I'll pass these on to our tech guys to look at. As it turns out, and the reason I've not chased this up is that it is planned that all our systems will be upgraded in a couple of months to Office and Sharepoint 2010.
