I have just installed Comodo, and restarted the computer. Upon rebooting, I loaded Comodo, but the app monitor, component monitor, and network monitor all failed to start. I receive error messages about these monitors from Comodo, but when I go into the program and try to turn them on, I cannot select “Turn on.” “Turn off” is already selected, and clicking anything else does nothing (the selection box is not even filled in). I have reinstalled the program once already, so any help would be greatly appreciated.
G’day,
When you installed, did you install the app to the default folder?
Ewen 
Yes, I installed comodo in the default folder under c:\program files.
Forgot to ask, what OS are you running (W2K, XP 32 bit, XP 64 bit, Vista - any flavour) and what service pack level is it?
Ewen
I am running windows xp pro sp2 all updates installed as of 4/18/07.
Does anyone have any ideas for this issue? I have uninstalled and reinstalled Comodo twice, and I have checked the registry for any entries related to “comodo.” The install goes fine, but Comodo gives me the “_________ failed to start–reinstalling the app may fix the problem” when windows first loads. All three of the comodo applications/sections fail to start.
CAn you check if the firewall services have started. If they haven’t can you set them to Automatic and reboot.

Is that done via services.msc? if so, for what am I looking? Comodo or the app names themselves? Thanks.
Yes, in the services.msc, look for Comodo Application Agent (cmdagent.exe). CFP only has one service here. Another location is to check if the driver (cmdmon.sys) is running in Device Manager (Control Panel > System > Hardware tab > Device Manager > View menu > Show hidden devices > Non-Plug and Play Drivers).
Where there will be two entries:
Comodo Application Engine
Comodo Network Engine
LM
Ok, I tried to activate the service, but I received the following error message: “Could not start the Comodo application agent on local computer. Error 5: Access denied.” Also, when I looked in device manager, I did not see any of the entries you listed.
That means the driver files are not even installed or missing. Search your computer for cmdmon.sys and inspect.sys. They’re located at C:\WINDOWS\system32\drivers in my computer.
Access denied…what if you disable the Protect own registry… option (Security > Adv > Misc > Config > very last option)?
