This forum is about which devices people should buy, not what ebook vendor they should use.

I'm trying to wild-arse guess what you're trying to do, and my assumption, based on reading between the lines, is that the books you've tried have an ADE download option available. Please correct me if I'm wrong.

If you want help with this problem, I suggest posting a proper thread asking for help, and including all the apps and software versions you've got, the exact steps you have tried, and the exact errors. I have no problem downloading Kobo ADE DRM epubs with my Mac and Adobe Digital Editions, so it's not an across-the-board problem. (You don't need the Kobo Desktop software at all, by the way, in case that's the software you've been trying.)

What country do you live in? Phone and live chat support is generally available as an option, but the support here is usually better for general questions that don't require the company's direct input.
