Today's kindletool_mingw works great on my win7x64, but the cywin version is missing DLLs. I tried using the cygwin DLLs from yifanlu's kindletool package, but that gives "entry point errors" from incompatible cygwin version. Searching my computer for "cygwin.dll" shows many different versions packaged in many different app folders, and history shows that trying to test all the cygwin DLL sets to find one that works with a fussy app ranges between difficult and overtly annoying. I strongly suggest you package cygwin DLLs known to work with this app into the kindletool-cygwin zip file). Meanwhile, back on the hunt for compatible DLL sets from the many on my computer...

Though for me, I am only DLL-hunting to test it for you and those who may download it. The mingw version works great as-is, so I no longer need to run it in a win32 VM.

Thanks for the update.
