Question Latest Calibre gives me the error "'calibre.app' is damaged and can't be opened."

I was using Calibre from July 20. Today I updated it to the latest version. Now when I try to open it, it says "'calibre.app' is damaged and can't be opened. You should move it to the Trash."

I tried downloading older versions of the app, with the same error message. Any version released on or before July 20 seems to work, while those that are version 0.9 or above don't work.

Anyone know what I can do to fix this? And is there any way to get this to work without having to enable "Allow applications downloaded from anywhere" if possible?

MAC?
There are specific instructions (on the download page) on HOW to install.

Yep, Mac. I've already followed those instructions. The latest OS X version, Mountain Lion, adds Gatekeeper to prevent unsigned apps from running. I had to change the setting to allow all apps to run in order to run Calibre; normally this isn't necessary, and I can just force open the app.

So, something is really broken with the Calibre app for Mac lately.

calibre is signed and works with Gatekeeper just fine. Make sure you are downloading it from the official calibre download site.

Yep I am downloading it from the official site (I normally download it from the "New update detected" dialog that Calibre pops up every time I open the app, considering there's a new version about once a week). The latest version appears to be busted because as I said, earlier versions were not signed as an "identified developer" and so I had to right-click -> open, but now I can't even do that. I can still download the older versions and do that, too, so something changed in the past few versions.

Works for me and the ~ 30,000 people that have downloaded the dmg for 0.9.3 so far. http://code.google.com/p/calibre-ebook/downloads/list

And the calibre dmg has been signed since version 0.8.61 which was released in July. I happen to know that since I had the unmitigated pleasure of paying Apple for the privilege of developing signed applications for their OS.

So if you're having trouble with the dmg, I suggest you investigate your machine for the cause.
