CLOUDASHUR KEYWRITER APP
If you also purchase the extra KeyWriter app (Windows only) you will need to register your key before using it (you can do that from the hyperlink placed in the email you will receive).
Once that is done you will also be required to enter your information to the app itself.
The KeyWriter app basically allows you to clone your cloudAshur onto another one so it too can have access to whatever you upload on the Cloud (or to local files if the same system is accessible to others).
To do that just mount your cloudAshur drives (select as master the one you'd like to clone), launch the KeyWriter app and press start (to check that for ourselves iStorage send us a 2nd cloudAshur module and as you can tell from the above pictures the procedure works as advertised).
