Client doesn't open. message about "allow NW.js " in firewall or anti virus settings?

The program is not able to open. I get message about "allow NW.js " in firewall or anti virus settings.
But in Win7 firewall settings, when I search for that file, to allow it, I cannot find that file, anywhere?

How else or what is suggested to be able to get past this blocked access issue? I'm not having similar problems with other software, so not sure what's the problem. But it does give this message about NW.js. Just not sure where to go from here?

Did you ever figure this out?
It seems I am having a similar issue. It started shortly after changing our AV software. I have tried completely disabling the firewall but that doesn't help.
Our issue is random, and rebooting the machine solves it temporarily but it eventually comes back after a while (days or weeks). I have about 20 machines running zimbra desktop and it happens randomly to different people at different times.
When they attempt to open zimbra, it flashes in the taskbar for a moment then goes away. Nothing they do will allow it to open except completely rebooting the machine. Even logging off of windows and logging back in doesn't work, but rebooting works every time.
Curious if this sounds similar to what you were facing.
Where would I find the message about allowing NW.js? Is this in a log file somewhere?

I have the same error. Any solution so far?

I am on 7.3.1, it was OK initially. But I cant remember what I did to cause it behaving this way. Cant even open the client now and cannot read all the mail that I stored in Local Folders.
If there is another way of retrieving the Local Folders archieve mail, I wont use ZD anymore.

When I re-install older version 7.2.5, I can at least login to the mail screen but it will not sync (with below error) and I cannot see the Local Folders mail.

Please help.
