I am using version 6.3.0.2026 of Finalbuilder and on several occasions I have found that when I want to exit the program, Finalbuilder freezes and won't close.
I did mention this to support several months ago with previous builds and was told it was probably due to my antivirus program (Kaspersky). I have now excluded FB and its installation folder from all antivirus activity, but still have this issue.
It's not reproduceable (sorry), but if I close FB 10 times 1 or 2 of those will hang the program. I then proceed to close the process from the Task Manager window.
I am using Windows 7 Enterprise (Spanish) and Kaspersky Internet Security 9.0.0.736 (English).
Is anyone else experiencing anything like this?
Regards,
Martin.

I have attached a log file from one of the times the program has hung.
HTH,
Martin.

Is there any news on the subject, as I'm still experiencing the problem?

Hi Martin
We’re still looking into it. The problem appears to be caused by something blocking the network licensing built into FinalBuilder. Can you tell kaspersky to allow udp for FinalBuilder? - this link might help : [http://support.kaspersky.com/kis2010/firewall?qid=208280578](http://support.kaspersky.com/kis2010/firewall?qid=208280578)
We’re looking into ways to detect when firewalls interfere and deal with this problem.
