Install instructions. 

Copy the folders "bin" and "XV2PATCHER" to the main root of DB Xenoverse 2 installation.
On a default Steam installation, that would be "C:\Program Files (x86)\Steam\steamapps\common\DB Xenoverse 2"

Your loose files go in the main install directory, following the same path that in the cpk.
For example, the file data/sound/CAR_BGM.acb would go in "C:\Program Files (x86)\Steam\steamapps\common\DB Xenoverse 2\data\sound\CAR_BGM.acb" on default install.

A remainder that movie files don't go inside data folder, but in movies directory.
