I have been downloading books from the public library to Adobe Digital Editions and then to my KOBO for years. Today when I attempted to download a book from the public library I clicked "OPEN" and instead of the file moving into ADE a Adobe Acrobat reader window opens and tells me that it cannot open the book into ADE. I must preface this statement by saying that I attempted to get help from the public library and they tried to get me to correct the default file that ADE uses to open. I suspect things got botched up. Adobe website suggested I use the forum for help. Here I am.
No replies! Maybe I should explain the problem better. When I download a book from the public library to my computer it will not go into Adobe Digital Edition (ADE). To correct this problem I am told to enter ADE.exe into the acsm file and I cannot do so. I consulted a computer expert and he also could not do so. Other files move readily into the acsm file but we cannot put ADE into the acsm.
Has you try if work when you go to Digital Editon and under File > Add to Library?
