There is even a special epub zip tool that handles rezipping of files to create an proper epub zip container for Mac OSX (on this forum). I am not sure what is available for Windows.

Then I try using the decryption tool and it has always worked well after that.
I tried that, and was told that my recreated zip was not an "adept epub."
