Pb during the update from nod32 v1 to v2

Hi !

We are updating all the computer machines from nod32 v1 to v2. I've followed the installation guide "Upgrading client workstations from the mirror (from NOD32 v1 to v2)". In my configuration results, the mirror directory is different than the one given in version v1. For some of them, the results were good, but for some others not. We had an error message "Kernel Error" during the update process, and after rebooting, the version 2 is actually installed but the mirror directory didn't change, without permitting nod32 to update the program components and the virus definitions. Is it possible to accomplish that automatically without doing it manually on each computer machine ? And if yes, How ?

thx in advance
