Adobe Digital Editions 4.5 will not open on Windows 10

[nandu007]

So I have installed ADE 4.5 on my computer with windows 10 and I was using it without a problem till yesterday. I shut down my computer yesterday after my reading, then today morning when I restarted my computer and tried to open digital editions 4.5, it will not open. I have tried uninstalling it and then re-installing it all over again without any success. I have not updated, installed, or changed anything since yesterday when digital editions was working properly. How do I fix this problem?

Thanks in advance.

Windows:

    Close all applications.

    Choose Start > Run.

    In the Open text box, type regedit and then press Enter. The Registry Editor opens.

    In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept

    Select the Adept key.

    Choose File > Export.

    In the Export Registry File dialog box, select Selected Branch under Export Range. Enter a name and location for the backup registry key, and then click Save.

    Right-click the Adept key and choose Delete.

    In the Confirm Key Delete dialog, click OK.

    Close the Registry Editor.

    Open Adobe Digital Editions and reauthorize.

Macintosh:

    quit Adobe Digital Editions.

    Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.

    If you are using 10.7, see https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html

    Open Adobe Digital Editions and reauthorize.

Hi! I am also having this same problem. Running on Windows 10 - I've tried uninstalling/reinstalling, rebooting computer, running as admin - all the same restults: I get the spinning blue "loading" cursor as if the it's opening....and then nothing happens. 

I tried these instructions above as well through the Registry Editor - tried the whole thing exactly as described twice but still the same results. 😕 No change - it acts like its about to load, and then never does.

Any other help out there??
