Ohhhkay
So reply here I must as my dear man Yoda would say.
Basically, if it's WebHelp, they open the WebHelp start page.
That's what the "gateway" is called.
However, it sounds as if your recipient is simply opening the
.ZIP and attempting to run it from there. Sorry, but that won't
work as everything that page would need is packaged inside the
.ZIP. She will have to first unpack it into the related folders and
files.
