Add checks to Windows for running in temp directory (running from archive), and proper file permissions (write/modify, to prevent things like Program Files or Windows, or other folders we couldn't know about that don't have proper file permissions). Instructs users as to what it discovered and how to fix, then exits. (#3097)
