That's a bug, that start menu item should not have been installed. You 
can't view the help unless R is running, because it is being generated 

You could create a shortcut with something like

<R HOME>\bin\x64\Rterm.exe -e "{help.start(); Sys.sleep(1000)}"

as the command, and set it to display minimized; it would run for 1000 
seconds before it died.  I don't think this is a great solution because 
it leaves that Rterm process sitting there, but maybe some variation on 
this would do what you want.

I will remove the code that generates the bad Start Menu entry from the

This seems like a bug report to send to the ESS list.

Those aren't distributed, but you could probably build them yourself if 
you get the source, as the originals are still in *.texi format. The 
Windows makefiles don't have targets for them, but if you have the 
tools, the Unix makefiles should give you the right incantations.
