Adobe Editions 4.5.3 does not start (System.Xml.XmlException)

[Guest]

On a Windows 10 Home Edition (64 bit) with latest patches as of Jan 3, 2017

A previous Adobe Editions 4.5.2 is crashing immediately with the following in the event logs:

Description: The process was terminated due to an unhandled exception.

Exception Info: System.Xml.XmlException

Problem solved. It seems the user.config file became corrupted, it had quite a few null entries on the end and the XML wasn't complete, as in <xml> </xml>

The file is located here: C:\Users\username\AppData\Local\Adobe_Systems_Incorporate\DigitalEditions.exe_Url_qyaa14c3q2yckzgdtukp5ltfvp1pdpdu\2.0.0.0

I deleted it and Adobe Editions started fine and recreated the file. I still have access to my DRM downloaded books.

Hope this helps anyone.

Thank you. I searched the web. I searched the forums. I found that several people were not able to open ADE after it had been working well, but nobody provided a solution. I finally found your post. It was relevant and it worked.  My problem with ADE happened like this: The program would open, but then would hang after plugging in my Kobo reader. Then I got get a blue screen. (I think they used to call it the blue screen of death) Windows 10 restarted by itself. The next time I tried to open ADE, I got the blue screen again, and the system restarted. After uninstalling ADE the system seemed to stabilize, I don't know whether uninstalling helped the blue screen problem, but I haven't gotten the blue screen since, even after I reinstalled ADE. But now ADE would not start. After a few attempts at uninstalling and reinstalling, and trying a few suggested solutions, it still would not start. Your solution was the only one that worked. Thanks again. By the way, I don't recall getting the  Windows 10 blue screen since I installed it in mid 2015. I suspect the problem was caused by trying using Apple software earlier that day.
