How to Know Which Software is Calling Out?
I have a software from a company that is out of business that I am trying to get licensed, using a name and serial number, however the software is "calling out" and then giving me an error message saying the license is invalid. I've set-up Windows Firewall to block the executable, both inbound and outbound and despite that, the software still fails, even though I have uninstalled and reinstalled it several times (idea being that perhaps there are registry entries left behind). In any case, the firewall rules should be blocking the inbound webpage from telling me the license is invalid, but for some reason it is not, and I suspect that the main executable is not the one that is "calling out" to check the name and license number. I've blocked several other .exe files from the installed directory to no effect. It continues to fail, and so now I want to use Wireshark to identify which software is calling out. It happens when you first run the software, so within just a few second window. Should not be hard to spot.
However, I cannot figure out how to get Wireshark to list what programs are accessing the internet, and years ago I remember clearly that it used to and so now I assume this functionality has been buried beneath all the other features, and I just need help finding it.
Thanks in advance.
Could it be that the licensed software won't run unless/until it has managed to talk to a license server, so whether you block it locally or if there is just no server out there to answer it, it won't make any difference?
If you just unplug the network altogether, does the software allow you to run it?
If I disable the network, the software still stops running and launches a browser window claiming my username and code are "invalid". I've deleted cookies and now I wonder if there isn't a registry entry flagging the software as invalid. I've tried numerous uninstalls and reinstalls.
