Hi guys!
I have been reading many posts about the whole kindle for PC and trying to find where kindle now days store its books on the PC so that I could used calibre to read my books. Not having any luck at this time

1)I have looked in documents under my kindle no go.
2)I have looked under AppData\Local\Amazon\Kindle\application\content no go
3)I have looked under AppData\Local\Packages\<Package Name>\LocalState or Roaming State or SystemAppData no go.
Reading many post on the forum I followed the advice to download
KindleForPC-installer.exe which I managed to do once and its the same problem I thought maybe I got the wrong download and tried again this time it would not let download and showed the windows app store instead.
Have I missed something or has amazon cracked down on the whole thing and we will need to wait around until someone finds a loop?
Thank in advance for the help
