Digital Signature is Invalid

Trying to download Adobe Digital editions. Using OS X 10.6.2.
But we are getting this:
“Error Downloading Installer
The downloaded installer has an invalid signature.”
The Adobe article is of course useless.
I think it’s the Proxy server. Will keep you posted/

  1. Same problem (no proxy here): Mac OS X 10.5.2, the tool had informed about a necessary update, but when I clicked on “install now” it just opened firefox without linking to any adobe page – so I removed the old tool and tried downloading the new version – same error message as you got it. If my local library would not insist on me having to read their e-books with this useless tool, I’d look for something else right away…

  2. ..solved for me. Adobe gives the following instructions:
    From your user directory, locate /Library/Preferences/Macromedia/Flash Player/www.macromedia.com/bin/open. …

    When checking, I did not find any files there (using cd) “/Library” is not the same as “/Users/…/Library”), hence there was nothing to delete

    The correct instruction (for Mac 10.5.2) is as follows:
    From your user directory, locate Library/Preferences/Macromedia/Flash Player/www.macromedia.com/bin/digitaleditions/
    and delete all files you find there.

    After doing exactly that, download and installation worked fine.

  3. Thanks GF, I’ll give it a try.

    For those that follow who are nervous about using the Terminal, select the path:

    ~/Library/Preferences/Macromedia/Flash Player/www.macromedia.com/bin/digitaleditions/

    Go back to the Finder, press Command-Shift-G and paste the path into the “Go to the Folder” dialog box that appears. Press the “Go” button and you’ll be in the folder so you can then delete the contents.

  4. None of this fixed the problem. However it was all something wrong with the Auto Updating. Adobe can’t seem to get it right like Apple and Ubuntu etc. can.
    I had to download the standalone installer, which worked OK.
