I got that also as one of the errors I have experienced over about a week.I finally uninstalled averything and renamed the "My digital Editions" foldersearched the registryand deleted everything ADE, searched the hard drive and deleted any other pieces of the programs, then reinstalled on a usb flash drive. That worked. I had a little trouble finding the "mydigital editions" ile again but did find it and was able to convert the ADEs to Kindle and regular acrobat and save them. It is sad when we are forced to use a free ptrogram and then the very rich and successful owncompany refuses to support the program because it is free, though compulsory. That experience has just decreased the chances of my ever paying for the new programs. I still have a working CS6, Acrobat X and XI, and lots of Corel and other products tht are as good as Adobe.
Had similar issue, all I could do was find a random old link to edition 4.0 and install that. Seems to work so far, touch wood. Follow these instructions: -editions/kb/cant-install-digital-editions.html
You can try uninstalling the software with 10bit uninstaller and make sure to remove any leftovers. Delete the folder in C:\Users\Current User\Documents\My digital editions. Then reinstall into a new directory under a new user profile or the public one- C:\Users\New user\New folder or C:\Users\Public\New folder. I used the public one and the software works again.

Libraries have been around for quite some time. One of the nice things about living in the digital age, however, is being able to check out books from the library in digital form. Ebooks, in other words. In order to take advantage of this, a computer user needs to have a library card, access to the Internet, and Adobe Digital Editions, the software used to download the book. You can then use this software to read the book on your computer, or transfer it to your ebook device.
When you press the Download button, a warning box appears that says you must complete the digital materials setup before downloading your file. If you already have Adobe Digital Editions on your machine, Click OK. If you need to install ADE, click Cancel and then select your device for setup instructions.
