How do I download digital editions to Windows 8.1

The eBook.de READER app allows Adobe Digital Editions books to be viewed on a Windows 8.1 tablet. The interface is in German but it does seem to work ok.

Is this a full Windows 8.1 tablet, in which case the standard Windows download page should be fine?

Or a Windows RT tablet, in which case ADE will not run.  In that case, try

DL Reader app for Windows RT http://apps.microsoft.com/windows/en-gb/app/dl-reader/0be254fa-1323-4bda-92fa-698fe502456c

Moved the discussion from Adobe Reader Touch for Windows 8 to Adobe Digital Editions.

Adobe Digital Editions does not officially support Windows 8.1 (not yet released) or Windows 8.
