WD SmartWare instalation problem

Sorry for my bad english. I have bought My Passport Essential 320GB Black, formated it from fat to ntfs and wanted to install SmartWare, i have downloaded new SmartWare from WD website.

The file was WDSmartWare_PP4R2_1_4_1_2

Unpacked it and ive got

1.WDSmartWare_ISO_PP4R2_1_4_1_2

2.WDSmartWare_Mac_Disk_Image_PP4R2_1_4_1_2.dmg

3.WDSmartWare_Mac_Disk_Image_PP4R2_1_4_1_2

4.WDSmartWare_Windows_Disk_Image_PP4R2_1_4_1_2

Then i followed the instruction from the website
