Is there a way to read out code from old pde file?

[tlow001]

Hello
I want to pick up processing again after years of inactivity, but when I open an old file I get an error:

I already tried to install an old veriosn of processing but I get the same result.
Is there a way to get the code file from the pde file without running it so I can rebuilld it in the latest version?
Thanks for any answers!
Tim
