I am trying to open a .acsm file in Adobe Digital Editions 2.0.67532


I keep getting the error E_ADEPT_DOCUMENT_TYPE_UNKNOWN


I have searched the forum and found this question asked previosuly - but NOT answered.


I would like to know what this means and why I can't download my book. 



Very frustrating to try and access customer support from adobe to be thrown over to a forum which has the same questions I seek the answer to posted MONTHS ago - and they are still unanswered.  There has to be an easier way!

    One reason can be a corrupt .acsm file.  Try redownloading the .acsm file if possible.


    There are lots of bugs in ADE V2.0, though I hadn't seen this one before.

    Try using v1.7.2 instead and see if that helps.

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

    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:

    Good luck, but warning the file is probably print restricted, so it may not be so easy to be done with that way.

    I suggest you double-check printing possibilities at home before assuming it will be easy to print in the office.
