Is it possible to run the Educational Flash video CD in the Adobe Cloud?
To add a bit more to what @Test Screen Name said, Flash Player is End of Life now and not supported. Even if you could install it, most browsers won't allow you to use it for security reasons.
Schools & content developers had 3-1/2 years notice that Flash Player was ending in Dec 2020. You should ask your school or CD publisher for replacement content that does not require Flash Player.
Adobe's partner, Harman, provides commercial solutions for enterprise customers that need help transitioning their Flash content to other supported technologies. See link below for details.
Hope that helps.
Thank you all for the answers. I expected this. As a second part of the question I'd like to check if there is a technology/script to convert the old Flash into the HTML 5 or similar new?
No, I'm afraid not. You need new content made with different tools.
