Updating problems

I have a programme called The Ultimate Troubleshooter. I find that since installing Comodo Firewall I cannot update that programme. It stops at 14% and I then get an Error message stating that the installation had failed. It had not even reached the end of the download!

As I am new to the Comodo programme, should I be adding something to allow these updates? It did ask me to allow the updater to have access and I agreed and it is listed.
