Neither of these works for me on Windows 7. [...]
I've just tested on Windows 10 with R 3.4.3 and current gretl snapshot
and all is working OK here.
There are a few changes in today's snapshot that might make a
difference. One change that's relevant for testing is that the --debug
option for gretl.exe, which somehow got disabled lately, is now
restored. So if the above methods are not working for you, please try
running gretl with --debug and see what's coming out on stderr; there
should be some chatter about initializing R.
