Folks, since installing the previous Visual Studio and installing 2015 I can't open help builder projects (*.shfbproj files) in my solution, they say "incompatible". I reinstalled the latest help software and it all installs perfectly and ticks all the boxes to say all of the VS support is ready. I can't find any useful help on this and I'm not sure which component to blame. The help builder GUI runs fine by itself. So it looks like some plugin for VS is missing, but all searches are futile so far.
Any ideas anyone?! -- *Greg K*
