direct export pug-in

I am using Endnote x2 now and want to export citations directlyl from WoS to endnote desktop. I downloaded the plug-in. When I installed it, it said “does not contain a valid copy of reference manager 7”. Anyway, I installed. But it doesn’t work. When I click on the export button, I am still prompted to save the file? I wonder where the plug-in for endnote x2 is? Thanks.
