Using manual offline Thank you. Once I made a copy of it all in a folder that was not related to My Documents, it works just fine. MY Documents would launch the index but take me to links in a temp directory which told me I needed to be online.

I open the index and genindex from blender.org and it launches Internet explorer. I can read the index page fine, but clicking on any sections tells me you're not connected to a network. In the address bar it shows a hard drive location. It won't open links to any sections unless I'm online

I can't get the manual to work on a pc without internet. It always launches a browser. I've downloaded the manual that says it's for offline use. Any ideas?
If you downloaded a zip file from here: https://docs.blender.org/manual/en/dev/ , then you can open it with your browser but you don't need internet for display the pages. So you can read it offline.
You can see the web address in the browser's address bar is pointing to your harddrive, not web.
