Estimated Sirs : The soft annouce from a new version actualization, after click to proceed, it start advicing from a 1% of completion and keep there unmoving from 3 o 4 hours, not go ahed more than this 1%. My OS is Win XP SP2 64 bits, my actual version of Comodo Firewall is 5.10.228257.2253. I can’t confirm but at shout down, the OS keep hold, till now I can’t check if this insatisfactory actulization it’s responsable for this.
If the problem is still there and you want to update to 5.12 please do a clean installation of 5.12.
You can export your active configuration before uninstalling 5.10 and import it in 5.12.
