How come I get "This file is version 20.0" error message when I only have Corel X7 and have only used X7 to make my files?

Ive only ever used CorelDraw Suite X7 Student version.

I installed my X7 suite and transferred my files to my new computer and when I try to open my files I get "This file is version 20.0. You must upgrade your program to open this file"?

But even File Explorer shows the files as "X7 Graphic"?

What's going on?
