How can I open some really old Version 5.1 files?

I have some ancient version 5.1 files with important contents which I need to use. When I want to open or import these files, I get a message that this version is no longer supported and cannot be opened. Is there a workaround? Can I perhaps install an older version of CorelDraw to open these files? I am using Windows 11. If so, where can I get hold of a Version 5 copy? If anybody knows an answer, I would sure appreciate it. Many thanks in appreciation. Stefan
