Simultaneous install of Comodo and ZoneAlarm?

Is there any reason why a machine couldn’t have both ZoneAlarm Pro as well as Comodo installed at the same time, so long as only one was active at a time?

Would this cause any problems whatsoever? And for what it’s worth, we’re talking about Win 7 x64.

CIS won’t allow you to install if it detects ZA. There are several applications in its list of incompatibilities that will cause this behavior.

Ah, well, so much for that then.

Thanks for the info!
