Changes to the reading environment on desktop PC

Considering the below perspectives comprehensively, we have decided to concentrate on offering and developing the Browser Viewer function and not further update the PC Viewer App.

– Type of functions planned to be added on viewers (including apps on smartphone/tablet)
– Facilitating SNS accounts’ convenience
– Security measures in accordance with OS/browser update

Therefore, the followings are the last version of the PC Viewer App.
BOOK☆WALKER for Windows: ver.1.2.10
BOOK☆WALKER for Mac: ver.1.2.6

We may also stop distribution and usage of the PC App without prior notice due to OS update and/or security countermeasures.
In this case, the Browser Viewer will become the only option to read eBooks on desktop PC, which requires a stable internet connection.

Please see details on [Important Notice] Changes to the reading environment on desktop PC (Dec.20, 2017).
