Adobe Digital Editions PDF file not being decrypted

[rgoubet]

I just installed the very latest version of Calibre (5.7.2) and DeDRM (7.0.0b4) on Windows 10 and attempted to import a PDF file protected by Adobe Digital Editions, but the file isn't being decrypted. This used to work in Calibre 4.x. No error message or anything visible.

DeDRM 7.0.0b4 still appears to need some work for Adobe DRM PDFs. You can either go back to DeDRM 6.8 on calibre 4.23 or wait until the next DeDRM release.

No error for the OP because they weren't in debug mode when they imported the book. But you will get an error message when trying to convert a book with DRM. Same recommendation ...use dedrm 6.8 with calibre 4.23 or wait to try the next dedrm release.
