Playing old projects

I have some Cubase projects that are make in Cubase VST 3.5. Really old stuff from the last 90’s. Now, almost twenty years later, I have lost the install CD and the dongle so I am not able to listen to my project anymore. I have stopped making music for many years ago so I do not own any Cubase software now (or any other music software for that matter).

My question is:
Is there a way for me to be able to just listen to my old projects without purchasing a brand new expensive software?

Yes, try to get a used version from ebay.

Well, you can buy a new Steinberg key and run a demo for Cubase. You will have some time to open, listen and export tracks and mixdowns
