Does Anyone Know How To Use Pluginsx86.exe ?

I know BitDefender has two types of offline update packages for BitDefender 2010, one is pluginsx86.exe and the other one is weekly.exe.


I wanna know how to use the first one. Because when I double click it, a window which asks me where I will extract it appears, and after the extract finishes, I open the file folder and find some files in it. I try to copy them to the destination:


C:\Program Files\Common Files\BitDefender\BitDefender Threat Scanner\av32bit_15411\Plugins


A window which tells me I cannot do anything to this folder appears.


So I ask here that does anyone know how to use pluginsx86.exe ?


Thx in advanced!
