When I download the latest installer, dragging "CoTinstaller.exe" into a folder gets blocked by ZoneAlarm, which reports it as containing the Trojan Dropper 'Win32.Convagent.gen'. The Kaspersky website forums note that various C++ compilers can produce code that triggers this detection.

It's a known false alarm.
