Say, when attempting to register the Help Builder in Visual Studio 2012 Ultimate it does not 'take'. I actually have 2008, 2010 Ult & 2012 Ult so maybe that's causing the issue. I was able to add and remove (multiple times) the connection from both 2008 & 2010 without any issue so it's just 2012 that's giving me fits.
I'll go ahead and uninstall the two earlier versions, reboot and try again but thought I'd mention it to you in case you had any suggestions.
Thanks.
Doug
