I have a home automation system and one of the controllers is no longer supported by the manufacturer. A separate company developed and sold a PC-based application for configuring and programming that controller. That software company went out of business a couple of years ago. I found a person who has the original installation disks for that PC software. Is it illegal for him to make me a copy of those disks? What happens to the copyrights that a company holds after the company is dissolved and no longer exists? The person with the software is reticent to make me a copy - thinking that it would be illegal.
