what you describe here is exactly the same as what happened to me while installing 4.33.
Do you actually use Comodo Firewall? Try to shut it down or switch the application (Falcon Setup) to safe in the Firewall menu.
I hope it’ll help!

As soon as I disabled all modules everything went as planned.
I cannot think of words to thank you enough!
If someone else finds this same problem disable all modules in comodo. Exiting the aplication is not enough.
