 Instructions for installing Wine, Kindle for PC, Adobe Digital Editions, Python and PyCrypto
 --------------------------------------------------------------------------------------------
 
-These instructions have been tested with Wine 1.4 on Ubuntu but are now very out of date. 
+These instructions have been tested with Wine 1.4 on Ubuntu but some of them are now very out of date. Parts of the instructions (those relevant to Kindle for PC and Python, but not Adobe Digital Editions and PyCrypto) have been tested with Wine 3.0 on Ubuntu.

+If you only use Kindle for PC, version 1.17, then you won't need PyCrypto nor Adobe Digital Editions, so you can skip the pertinent steps.
 
  1. First download the software you're going to to have to install.
     a. Adobe Digital Editions 1.7.x from http://helpx.adobe.com/digital-editions/kb/cant-install-digital-editions.html

  2. Install Wine for 32-bit x86.  (e.g. on Ubuntu, Open the Ubuntu Software Center, search for Wine, and install "Wine Windows Program Loader".)

+ 4. Navigate to "Install an application" and install Kindle. Alternatively, run `winetricks kindle`. Note that using `winetricks kindle` will give you version 1.20, which might not be what you want.
  5. Install Adobe Digital Editions. Accept all defaults and register with your Adobe ID.
- 6. Install Python 2.7.x using `msiexec /i python-2.7.8.msi`. Accept all defaults.
+ 6. Install Python 2.7.x using `msiexec /i python-2.7.8.msi ALLUSERS=1`. Accept all defaults. Alternatively, run `winetricks python26`. However, if you do that, the automatic retrieval of keys (described in the next section) will be impossible, as dedrm_src/wineutils.py currently hardcodes the path for Python27. For manual extraction, you will also need to change Python27 to Python26 in step 2, below.
  7. Install PyCrypto 2.1. Accept all defaults.
- 8. Unzip DeDRM_plugin.zip and move kindlekey.py to somewhere in drive_c, such as ~/.wine/drive_c/DeDRM/libraryfiles/kindlekey.py.
- 9. Run `wine 'C:\Python27/python.exe' 'C:\DeDRM/libraryfiles/kindlekey.py'`, or wherever you copied kindlekey.py to.
- 10. Import the resulting key file to the Calibre plugin through the Kindle for Mac/PC ebooks option.

+If everything has been installed in wine as above, the keys should be retrieved automatically.
+
+If you have a more complex wine installation, or something goes wrong, you may enter the appropriate WINEPREFIX (by default ~/.wine) in the configuration dialogs for Kindle for PC and Adobe Digital Editions (Preferences > Advanced > Plugins > File type plugins > DeDRM > Customize plugin). You can also test that you have entered the WINEPREFIX correctly by trying to add the default keys to the preferences by clicking on the green plus button in the configuration dialogs.
+
+Alternatively, if that also doesn't work for some reason, you can extract the keys manually.
