h2o from R on Windows gives curl error: Protocol "'http" not supported or disabled in libcurl -

i've run h2o r on linux machine , wanted install in windows too. h2o not initialise me. full output pasted below key seems line

[1] "failed connect 127.0.0.1 port 54321: connection refused" curl: (1) protocol "'http" not supported or disabled in libcurl 

judging this , this experience might single quotes v double quotes somewhere; seems unlikely because no-one able h2o / r / windows combination working , gather people are. on other hand, this question seems suggest problem curl installation may not have ssl enabled. downloaded curl scratch this wizard recommended on h2o page, selecting 64 bit version, generic, , selected version both ssl , ssh enabled; downloaded , added folder ended in windows path. no difference.

i've noticed java runtime environment old , update well. on face of it's not obvious that problem.

any suggestions welcomed.
