Last couple of days my techs and myself have tried installing on several systems, all fail...
Outlook flat out crashes when the social connector is installed, and the LinkedIn does not work with the 2010 shipping connector.
Sadly, the standard 'uninstall' from the control panel does not work, as it leaves the two 'socialconnector' dlls in the Office14 folder.
This needs to be addressed before a lot of non-tech users try this on, as it is not an isolated problem. As I said, we tried this with several configurations (only 32bit, etc, etc, as the sites state). I assume MS has some peeps on this, as I told my techs to not take time to debug it out and find the problem.
