comodo update error A connection with the server could not be established

as the title, I am running here windows 8 x64, I have tried almost everything, when I run the tests everything was OK

when using ultrasurf with proxy port 9666 in Comodo the update will work

can anyone help please

it was in CIS 7 and now 8 the last version

Could you try the following:;msg769911#msg769911 ?

it worked a million thanks,

I did export my windows 8.1 registry key ( the only one mentioned ) from my windows 8.1 to my friends 8.0 and it worked,

big thanks, I tried almost everything,

it would be better to change the name of that thread to update error and not scan error

again thanks
