This version of PreviewHTML is not working with Notepad++ v7.5.8 64bit Build time: Jul 23 2018 02:06:36

What exactly do you mean by "not working"? (As a rule of thumb, the description "doesn't work" is useless in a bug report unless further specified).

Please describe the following:
* what did you do?
* what did you expect to happen?
* what happened instead?

FWIW, the plugin works fine with that exact version of Notepad++ on my machine.

Really?  The anonymous requester listed 64bit.  There still hasn't been a public 64bit release, so I don't see how it could work with exactly that version, unless you're using a private 64bit build of the plugin.

Ah, you may be right, pryrt; I seem to have missed the ‘64bit’ thingy.  In that case this is a duplicate of [240f1abc07].

But there's now a 64-bit version of the plugin available, so do check out if that one works.
