I\'ve installed Visual Studio 2012 RC.
I\'m working with TFS2012, and when I want to export a user story to excel I get the following dialog box error:
Last I checked the TFS addin didn't work with 64bit of office.
It may have changed since the 2010 version, but it wouldn't surprise me if it was still the case.

The fix for this turns out to be simple - see this blog post for details.
From the registry, when you see two keys under:
HKCR\TypeLib\{00020813-0000-0000-C000-000000000046}\
delete the highest one. In my case this was 1.8, but it will depend on your version of Excel/Office (the artical describes deleting 1.7). This problem does seem to return after some time (maybe after patches), so you may have to re-apply this fix unfortunately.
I'm sorry for the late answer but I was managed to avoid this error by connecting to TFS from Excel using TEAM tab. Then I created new list using TFS Query and it works pretty good
