From: Installation Problem Yet Again

I have just purchased Bitdefender internet security 2013. I have downloaded the unistall program for Mafee, change the UAC to never notify, changed the properties to unblock. Used the 2013 uninstall after each failed install. So where am I going wrong, At the end of the install I get bdagent.exe error followed by seccenter.exe the application was unable to start correctly (0xc000007b). Can someone please help? or it's back to Norton.


I am running Windows 7 64 bit.


Cheers


Pete
