Brian,

The html help file can be located in the NE directory tree. No website required.

For the PC, this is where the html help file is located:

C:/Users/<username>/AppData/Roaming/Moi/nodeeditor/nodes/extensions/help.html

By 'launch', I mean to shellExecute the html to the browser to view. Not launch a website location on the web. Although that can be done as well as starting external programs.

Thank you,

Wayne
