I have been using Bid Plus for 15 years and I would like to continue to use the older version. I bought a Samsung Galaxy tablet specifically so I could use the old version. Is there a way I can download it on my tablet?
No, you can't use the application on the tablet because it hasn't been released for mobile/handheld devices like Samsung Galaxy tablets. According to the official information, you can install it only on computers with Windows operating system. No mobile support is provided by the developers of Bid Plus.
Windows version only: https://www.bidplus.com/install/bpmm9000.exe
To get additional information related to other supported platforms or upcoming releases, get in touch with the developers. They should provide all the necessary details: https://www.bidplus.com/asp/contact.asp?09021300
