Ask yourself “why do I need SP 3”
From the minute I installed it I had a bushel full of problems, some users do some users don’t, I found myself in the do category. After the uninstall it was smooth computing, plus I was now able to install CFP.
I’m having the same problem. This is actually the second time I’ve had this problem. The first was with a slightly older version of Comodo Firewall (maybe 2 months old) and now tonight all of a sudden with the newest firewall version I’m getting access denied to everything. I can’t even open up the firewall console. I booted into safe mode and uninstalled firewall. Why would these Comodo all of a sudden decide to switch into ultra-OS lockdown mode? This is two version now. I’m going to hold off installing another version until I hear the issue is understood and resolved.
However if anyone else is having this trouble. I find the easiest solution is to boot into windows safe mode and uninstall the firewall program. I’m sure when you reinstall it won’t have the permission issues (at least not initially…)
BTW I am running XP Media Center with SP3 and the newest Windows Updates.
