Unable to open ADE 4.5 and epub files

I have a problem with Adobe Digital Editions (4.5.4) in Windows 10.  When I try to open ADE, an icon appears on the taskbar with a blue line (showing it is active), but ADE does not appear on the screen.  This happens however I try to turn it on, e.g. from the start menu, from a screen icon, or by right-clicking on an epub book in 'My Digital Editions' and telling the computer to open it using ADE.  If I try to open an epub (e.g. welcome.epub) and hover over the ADE icon on the taskbar, a thumbnail of the epub appears, but clicking on it just makes the thumbnail disappear.  When I then right-click on the ADE icon and tell it to close the window, a dialog box appears with the message (which I don't understand): "welcome.epub is not open from library, would you like to copy it to library?"  I have tried uninstalling and reinstalling ADE.

Has anyone else had this problem?  How can I get Adobe Digital Editions to open properly so that I can read my epub files?

The Version 4.5 has any problems. Better you uninstall it and install again 3.0.

Thanks for the suggestion — I tried doing as you suggest, but it made no difference.

No, this is the only ADE version I have. I uninstalled the earlier edition when I updated to 4.5.

That registry procedure didn't work.

 

I have Ebooks downloading from Kobo set to open with Adobe Digital Editions. (4.5.10)

Lately, it has stopped opening them. Instead I get a message:

"Unable to open X

Errors were encountered in this item"

 

Reinstalling and updating didn't help.

 

Took the advice to revert to 3.0 - http://download.adobe.com/pub/adobe/digitaleditions/ADE_3.0_Installer.exe

Also renamed "My Digital Editions" folder in Documents to "Digital Editions Old"

That worked, but don't know which action was responsible. Should have done them separately...
