    Cannot open ebooks format .epub with ADE 2.0


      With Adobe Digital Editions 2.0 I am not able to open an ebook format .epub. The error I get is: this is not a valid win-32 application, although I am using Windows 7-32 bit. With the former version of ADE I had no problems at all. I wonder what is going on, can anyone please help me? Thanks in advance,

          I don't know why you are getting this particular issue; that combination works for many people.

          It sounds as if something went wrong with your install.


          You could try uninstall and reinstall.

          If that doesn't help, try the much more reliable v1.7.2 instead.



          There are lots of bugs in ADE2.0 (and 2.0.1).  Try replacing ADE2.0 with the older but more reliable v1.7.2.

          (You can have them both installed at once if you like.)

          Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.


          The forum software is sometimes corrupting the link above.  There shouldn't be a blank in 'editio ns.html'.  The following redirects to the same page: http://tinyurl.com/diged172



          Some people have found ADE trying to upgrade automatically. 

          It appears (not 100% sure) that if you install ADE2.0 as a new install (not as an upgrade) that your 1.7.2 will continue to run.

          Probably best to say no if 2.0.x installation asks if you want to migrate your library.

            Thanks for the reply. I followed your advice and installed version 1.7.2 of ADE.

            What has changed is that it is now possible to open epubs, but only when I transfer them to a bookshelf in ADE. What I want is opening the epubs in my download folder by double clicking on them, but that is still not possible. I don't understand why this is not possible any more. Furthermore I don't want to transfer all of them to ADE because as far as I can see under the heading "author" there is no possibility to change the sequence of the names. I want it like this: Hoofdman, Louise and not Louise Hoofdman.       Greetings Mistik

              Sometimes the registration of ADE to Windows as the default hander for .acsm and .epub files does not work;

              that is what causes the double-click in Explorer to fail;

              especially in Windows 8/8.1, and maybe 7;

              this appears to be a bug in Windows (for once not a bug in ADE).


              Two possible ways round it.

              First, try to force it in Explorer

              Right-click on a .epub file (and repeat entire sequence for .acsm if necessary)

              Select 'open with' if on the list, 'open' if not.

              Select 'choose default program'

              Select ADE if it is on the list,

              If not select 'more options' and navigate to the ADE executable (may be at C:\Program Files\Adobe\Adobe Digital Editions\digitaleditions.exe)

              Now .epub/.acsm files should be associated with ADE, and double-clicking should work.


              Sometimes, Windows allows you to go through all that, but then refuses to make the association you have asked for.

              In that case, the only way I know is to use a third partly file association program.

              http://www.softpedia.com/get/System/System-Miscellaneous/Types.shtml works for me.


              For non-DRM books I suggest the use of the free Calibre rather than ADE.

              It is much more reliable and powerful, including sensible handing of author names.

                Hi sjpt,


                This is to tell you that my problem with ADE has been solved. ADE was

                not the culprit, it was my computer that probably still had malware,

                despite scanning with CCleaner. I found a program called Spywareblaster

                and after running it the computer acted normal again, so that I could

                reach 'open with' and make the association with ADE. All is fine now, I

                can open the .epubs in my download folder by just right clicking on them.

                I want to thank you for your fast and kind support in this case.

                Greetings from The Netherlands, Louise Hoofdman

                  Glad all now going well.


                  despite scanning with CCleaner. I found a program called Spywareblaster

                  CCleaner is an excellent programs which I use regularly, but it isn't designed against that kind of C***

                  For anyone else who thinks they may have similar issues, Malwarebytes Antimalware is an excellent choice,

                  run together with any high quality anti-virus.
