Wait I assume will check with a tech we talk to.
Kindly confirm if 3 User McAfee virus scan plus , expiring on 2012 is the programs you have issue with activation ??? ?
Also , let us know what is the operating system of the PC ??
I am having this exact same issue. I have the 3 user AntiVirusPro 2012. I have installed it, but it will not activiate. I have used the removal tool and tried reinstalling it and still the same thing. I have tried removing it and downloading it from the web, from My Account, and it will not download. I am using Windows XP SP 3. Any help?
1 No 2 PCs with same name?
2. If you had another AV installed ensure you removed it fully with its own removal tool. that will stop activation if not done.
