3DConnexion is blaming this on Solidworks changing something in the code
because of "stability" issues that prevents the 2.8.2 addin from now
working. What you will need to do is download the latest USB version
which is 3.5.6. If you already have 2.8.2 installed then when you
install 3.5.6 ONLY install the Solidworks addin. DO NOT INSTALL the main
drivers. If you go to the 3Dconnexion forum, it gives you some
additional information as well.
