I also am looking to download new kobo books into calibre. I have been using this method for ages so I guess I need ADE for windows 11. I was using ADE 2.0 on my previous win 10, so my question is can I still choose any version of ADE or is there only one available? Will it still work the same way to download to calibre?

I have Obok dedrm already on my calibre and intend to buy from kobo and remove the drm as I usually do. Which ADE should I download?
