I installed it on a VM of my desktop and it broke Comodo some kind of memory error. I uninstalled and reinstalled and it's OK now. I see people over on VMware are having issues the thread gets twisted up with Server 2008 hosts. I see it's in automatic updates this morning. I'm a little more cautious about grabbing newest updates and drivers. This spring my video card got fried with a bad driver update, it messed up the fan function. I think I'll wait a bit!
