Please can you help me, am getting this error (0xc000009a error) when am trying to download McAfee in windows 10. I tried MVT and MCPR but I still have the same error.
As the other thread was so old and had been solved, I moved this to your own thread.
Windo0ws 10 is not supported as stated. It no doubt will be by the time it goes RTM
We can't help you with software running in Windows 10 - it's only in it's early stages. I would simply rely on the built-in Window Defender for now, it contains anti-virus, and Windows Firewall for your protection.
I wouldn't be running it as a a main system either (if you are). Best run it in a Virtual Machine within a supported system then all bases are covered again. It installs OK on Oracle's Virtual Box for instance.
