I have a laptop, a kobo and ADE and everything works fine. I have admin rights on the laptop, and the ADE is authorized for me and computer, and I use it with my library account.
My wife is also a user on the same laptop, and has her own login name and email. She is thinking of buying her own kobo.
We would like to install a second ADE on the same laptop so that we can keep my books and her books separate.
Is this possible, and if so how would we go about it?
You really don't need to do that, because you can 'switch' users. You can
use the 'deauthorize/reauthorize' process described in ADE Help. It's
equivalent to logging off and then logging back on with a different user ID.
