Bump.... Why this happens? How to fix it?

Endpoint Protection cannot be installed on a computer that is running other security programs. Sometimes, even if you remove other security programs, they do not completely uninstall. You must be running a genuine version of the Windows operating system to install Endpoint Protection

Is your Windows 7 Legit?

Yes it is legit.
However i have another machine on which I see same error.
