I have the same problem after a fresh install of Windows 7 Pro with a Lenovo configuration. I have never been able to enter the main window. I also tried uninstalling and reinstalling CIS.
cis.exe exists and goes into process list when started, but disappears after just a second.
CisTray.exe is running.
Edit:
Doing section A of “Most Effective Way to Reinstall/Update CIS to Avoid/Fix Problems” Comodo Forum and then reinstalling gives the same result.
Cis.exe appears to be crashing. Can you look in c:\ProgramData\Comodo\CisDumps if the crash gets logged by CIS? Do you have other security programs installed. If so which one(s) run alongside CIS in the background?
Yup, there is one dump generated per attempt (attached).
There are no other security solutions installed as far as I can see.
When looking today a cis.exe was actually running, don’t know what triggered it, but still no main screen available and after shutting it down it does not appear again.
Thank you for the crash report; it’s not readable for me.
Can you start the main window using the shortcut on the desktop or start menu when you can’t start it from the tray? We may be looking at a bug and I am trying to establish what the extend is.
