Adobe flash discontinued and adobe digital editions no longer opens. How to access the files?

Goodnight. I own some ebooks that can only be read in adobe digital editions. A few months ago my computer, whose operating system is windows 10, was updated and adobe no longer opens on my computer, in previous versions of windows it worked. When I run the problem solving it appears that the program is incompatible with my computer.

I wrote to adobe support and they told me they discontinued adobe flash last year and without it adobe digital editions doesn't work.

How do I now open my books?
