You need to download and install the same OS (4.2.2)that is on your device on to your pc as well as whatever version of the Desktop Manager you want to install. You need to install both.

I'll add that you need to install a version of Desktop Manager that is either the same or a NEWER version than the os. So I'm on 4.5.5.52 operating software and 4.5 DM, but I believe that the new Desktop Manager 4.6 will also work with my phone. However, DM 4.2 won't work properly with a Blackberry running os 4.5.
