As of February 28, Sony Desktop will no longer be supported by Rakuten Kobo. This means it will no longer receive software updates, and will not be able to connect to the Kobo eBookstore. Kobo apologizes for any inconvenience this may cause.
Rest assured that no items in your Kobo library will be affected; you will continue to have access to all reading material you have purchased or downloaded from Rakuten Kobo.
You can still download the free Kobo App available for iOS and Android smartphones and tablets and read with Kobo on a device you already own.
Alternatively, you can download the free Kobo Desktop App to read your eBooks on your PC or Mac desktop computer.
