Thanks 4 the response..
I have no any other anti virus installed, nor have pre version of Macfee, mine is total a new system, but couldn't find any reason why installation failed.
Even before my trials i have turned off Windows firewall, UAV, Windefender and IE protected mode too.
In the Total protection Installation only Site adviser, OEM support and parent control are successful, but anti virus, firewall and ant spam failed twice
Any other suggestions are appreciated.
Regards
