I've recently set up org-protocol as well and while I can confirm that
it prepends the full executable path, I don't get the extra "/" and
org-protocol works fine. And your link worked fine, except that I had to
obviously change the template name. From what I understand the additionÂ
of that "/" is extremely weird, since protocol just passes the whole
string to the command.
What version of org are you using? I'm currently using org-9.0.9
installed from a zip.
And to be sure maybe you should try something like:
emacsclientw.exe
"org-protocol:/capture?template=w&url=http%3A%2F%2Fjira%2Fbrowse%2FSDST-705&title=SOMETHING&body="
