-How-to:
+The latest Scuolabook tool can be found at Hex's own blog:
-1) Make sure you can read all PDF files on Scuolabook Reader.
-2) Run Scuolabook DRM Remover.
-3) Decrypt your books.
-
-Note:
-It is recommended to use Scuolabook version 3.0.3 and refuse all updates
-because the encryption algorithm may change making this tool useless.
