problem using adobe digital editions 4.5 in windows 10
Cannot get ADE 4.5 to open e-book from library
I get the screens shown below
Downloading Content then Unable to download.

I then uninstalled then reinstalled ADE but the installation failed at Error Opening File for Writing see below

Pressed ignore which brought up screen shown above

Pressed ignore and ADE installed showing completed

I then try to load library e-book into ADE and am back to start fulfilling and unable to download
Any help would be appreciated.
