When trying to download Adobe Digital Editions 1.5, I repeatedly receive the Can Not Download to Hard Drive message on my G4 Mac running OS 10.4.11.
Installed several times is Adobe Reader 8.1.2. But it always crashes soon after opening unless I (based on online recommendations somewhere) UNcheck the updateracro.plugin (for automatic updating) in "Get Info" > Plug-Ins. Before I discovered this work-around, every version 8 Adobe Reader I have tried has crashed soon after being opened.
Adobe Reader 7.0.9 (updated to 7.1.0) still works fine, except (after trying to upgrade to version 8 ) File > My Digital Editions > "Could not create an EDB database: Unable to load the specified database driver dynamic link library".
All this is a big problem for me because I have lost access to the digital edition of a programming manual I purchased (& have a copy of the license key for.).
After specifying in Get Info, that this ebook should be opened by v. 7.0.9 (7.1.0), > error message "Unable to download necessary files at this time. . Adobe DRM Activator error (client code 9). Fault location: 9. Contact Customer Support."
As long as I can read this manual (as I formerly could), I will be happy using whatever version of Adobe Reader.
