More simple way is - click right mouse button on the error (on "Distill failed for unknown reasons") and select "Reveal in Log".

THANK YOU. I have been wracking my brain over this after multiple failed archive attempts. This immediately solved my problem – erparker Sep 22 '16 at 22:52
@OshadhaPunchihewa It was a problem with icons files (in my case), please look at the your log for details. – Maxim Firsoff Dec 03 '19 at 10:09

This may be an issue with an image that is saved with the PNG extension that is actually NOT a png file (frequently this happens when using "save as" on a PSD and naming it with .png while forgetting to actually convert the file).

This has been answered before here.

For me the solution was THIS.

(Note: I had no .psd as .png, etc.)
