Antivir (Personal Edition) en Windows Server 2008

Para instalar Antivir en W2K8 Server:

1.) Start --> Run --> Regedit
2.) Go to HKEY_LOCAL_MACHINE --> SYSTEM --> CurrentControlset --> Control
3.) Now change the permissions of the folder "ProductOptions" --> add your user account (for example Computername\Username) and deny yourself the read rights for the whole folder. Be careful not to deny the whole rights for all administrators or something like that (I tried that first cause of a black out and it leads to windows not being able to boot).
4.) Now you should be able to install Antivir PE
