May we know McAfee program which you are trying to install.
MCAFEE ANTIVIRUS PLUS FOR WINDOWS 8
BUT I HAVE WINDOWS 10
While we wait for the tech to return can you please elaborate as to when you see this error. I notice no other reports on the forum of it.
I assume during installation try uninstalling the program via
and then reinstall as this could be caused by corrupted downloaded installation files.
