My book essential - problem with automatic backup

have a problem with my book essential 1TB.
I changed my internal HDD in notebook. Now I have SSD disc. My book I used to use as external backup device. But when I connected my book essential to notebook again, nothink happened…I supposed, WD SmartWare should to install on my new SSD disc…I am only able to use My Book as an external HDD, but not as automatic bacup device, using WD SmartWare…
Please, what to do, to instal WD SmartWare on my new SSD? WD SmartWare installation file should be placed on my book in factory…but I am not able to start it…
Thank you in advance
WD support does not work…
