Cubase SE 1.07 install files

Hi there. I have a valid license/serial for Cubase SE 1.07, which I bought at a store ages ago. Sadly, I have lost the install CD somewhere in the past 10 years. I put in a call to Steinberg support, but they say they don’t have the installer files any more so I’m out of luck. Am I really out of luck? Is there anywhere else I can get my hands on the install files for Cubase SE 1.07? I intend to install it using my serial number and activate it using my USB elicenser, so no issues there, I just need the actual install files.

Thanks!
