Just got HDpro-2020, running under Windows 10 Pro. It looks very promising but requires a lot of steeping in how the program is structured. There are lots of great resources, some inherently online (like video guides) and others (like the Reference Manual, general User Guide and building-case-specific user guides) in PDF that can be downloaded as needed, but. make sense to keep offline, rather than download every time.
Unfortunately, from the Help menu, HD defaults to downloading the PDF files every time; it does not recognize what it has already downloaded. I've tried putting them in various likely places where the program might be smart enough to look for them (and find them first before going to download), but to no avail. If there is such a place, I would be grateful for a pointer in that regard.
Short of that, I have resorted to putting these references in a "Home Designer Guides" folder, with a Windows link to the folder (and try to avoid the HD Help menu in this regard). That works, but is still slightly clunky, and I'd like to find a more elegant way to integrate with the HD program. Are there any better solutions? For that matter, there is an intriguing "Manual" folder, inside the HD program folder, that appears to be the skeleton for an offline manual written in Qt5 -- but it does not seem to do anything (yet). Is there any information on this?
Finally: I realize that a "meta"-type question like this might be better directed to the Support forum, but my browser warns me, "The owner of support.homedesignersoftware.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website." Is this a known issue? - a problem? - a cert out of date?
