Help is broken and/or not installed?

[jupiter]

When I press F1 for help a window pops up that says 2.2 Image Window - GIMP Help Browser but there's nothing in it (empty white page). Then after about 30 seconds there's a page of help called "2.2 Image Window" but no other help pages - I only get that one. I clicked on something and got a message saying something like "You need to install help in order to use the help" but I can't do that because I don't know how - I would need the Help to tell me how to install the Help in the first place(!)

This is a brand-new installation of 2.10.30 on a brand-new installation of Win 8.1
