I'm having some trouble with this.
First off, it doesn't seem to work in Firefox. No big deal, switch to IE.
In IE, I get to the page and see "ObjectARX Reference For .NET", but if I check it, the "Update VSExpressCC" button becomes disabled. If I uncheck it, the button becomes enabled. So it seems I can only update the VSExpressCC if I don't include the ObjectARX Reference.
I try the integrated help for VSExpress, and it tells me to do things like look in Tools->Options->Environment->Help. I go there, and all I have in the "Environment" section of Tools->Options is "General", "Fonts and Colors", and "Keyboard". I don't have a "Help" option.
Whassup?
