?ADE 4.5.2 compatible with Windows OS10

Question

Recently downloaded ADE 4.5.2 and when I try to open a book that I have downloaded from my library I get Error: check activation. I have seen various ways to do this but none of them mention OS 10. All talk about earlier versions? Any help greatly appreciated.
