As further detail, I managed to successfully download the MSN .Net4 requirement (or whatever it was) and the icon has appeared on my desktop. I am not computer proficient and wouldn't know where to start regarding 'administrator' access. I'm particularly unimpressed with Adobe not dealing with my enquiry themselves. Here's hoping you guys can help. Cheers
I have the same problem, could not download to Nook because it said my device was not authorized, yet when I click on the Nook it says it is... very frustrating. Adobe Digital Editions is not user friendly at all!!!!!
