Here is my idea :
- Install NOD32 with silent switch /SILENTMODE /NORESTART.
- We import the .REG file that we previously exported from preinstalled version of NOD32.
- Fix the paths we the following .CMD file :
CODE
REG ADD "HKLM\SOFTWARE\Eset\Nod\CurrentVersion\Common" /V "QuarantineDirectory" /D "%systemdrive%\\Program Files\\Eset\\infected" /f

The main idea is to replace every occurrence of the drive letter like © with the (%systemdrive%) so it will be correct whenever you choose different partition not just C.
I Hope this will be useful for someone.
