After I installed Visual Studio 2008 beta 2 (Orcas) and the new TFS explorer, I was trying to export my tasks to an excel file from Visual studio 2005 and encountered this error:

It says there is a problem with the installation of the Visual Studio 2005 Team Foundation Office integration components.   Luckily I was able to export the tasks to excel using Visual Studio 2008 beta 2, but now when I want to integrate with office and TFS I need to use the new beta.  I hope this is the only issue I run into, but I will keep you all informed as I run into issues.  Overall, I like the new beta, but am having a hard time figuring out when to make a new project use it as I will need to have all of my developers use it also for a particular project since we can't open the projects in both instances.
