I'm running 10.6.8 on my MacBook and can't seem to get Calibre to install. I took it out of the download section as recommended and stuck it on the desk top. Clicking on it give me "Calibre 0.9.39.dmg Not recognized". The download seemed to be adding time instead of subtracting time for a while before it got shorter but said the download time was well over an hour. At about one hour, it suddenly showed that it was all downloaded. Did it twice since the first time it gave me the same response.
Any thoughts as to why it won't install?
