In past years I always upgradet the older version of Internet Security to a new one without a problem, but now when I upgrade the Internet Security 2010 to a new version it tells me thet this key is not valid for Internet security, so it works only with Antivirus Pro 2011.
My question is: Why that?
Is there a way that i can install BitDefender Internet Security 2011 with the registry key i posses or I have to downgrade it to 2010?
Cheers.
