battlefield-heroes game install problem

My son wants to play battlefield heroes but even in trainingmode it won’t work.
https://play.battlefield-heroes.com/playnow

If you are on the page and login to the beta corner and click the yellow “play Now” button in the left upper corner the game loads a plug-in for firefox “Battlefield Heroes Updater”. After restart Firefox and going to the same site and click the yellow button a windows comes up telling there is a update and but it can’t install due to an error.

This error is Comodo CIS because we can see the program stop the action by D+ but how do we solve this.

I already had Battlefield Heroes installed for a start.
When trying to play I got some pop-ups from the firewall and D+, there I select “Trusted Application” and move on.
So far it works and I can shoot round and round.

Eljo can you post a picture of D+ blocking it?

There is no message or pop-up or what ever, only a entry in a list that it has been blocked.

Have you added this file with full path to your own safe files?

This rule was put there by me a day ago but did not do the trick.
