Couatl engine hasn't started

[ESchell]

At first a warmly hello to everyone in the forum
I know there are  a lot of existing posts regarding this issue and I read them all but none of the suggestions worked.

More or less ten days ago, I started my Sim (Prepare3D, V 5.1) and I got the message, that an update for GSX is available. I stopped the sim and started the Live update.
And at this point, my problems have started:
- Although the program downloaded the .exe files, the process stopped. So I searched for a solution and one of the suggestion was, to install GSX from scratch. And I did.
- After installing I started the Sim and I wanted to register my installation through the addon-manager, but I got the error messages as per subject.
-Again, I tried to fix the problem and searched for a solution. And I followed all the proposals in the various posts.

- The folder Addon manager is excluded from antivirus scan (I use NORTON 360)
- I deinstalled/reinstalled the VC++ libraries
- I executed the simconnect.msi

And now I have no more idea how to fix the problem.
Hopefully someone can help me.

I attach the couatl.log

Thanks in advance

attach the couatl.log

The log shows you haven't got the latest .exe, likely because the antivirus has mistakenly blocked it.

- Configure the antivirus to add the whole Addon Manager to the antivirus Exclusions

- Run the FSDT Live Update again

Hello,

thank you very much for the quick reply,
Although I added the "Addon manager" to the scan-exclusion list before, I did it as advised again.
Additionally I shut down my AV completely and the "common" Windows firewall as well.
At first I only executed the live updater - now success.
Then I installed the GSX L2 again and executed the Live updater - no success.
I know, that in more than 90% of the issuses the problem is in front of the screen, but I have really no idea, what happend.
And please note, I am only a user

At first I only executed the live updater - now success.

Which is what I asked to do.

Then I installed the GSX L2 again and executed the Live updater - no success.

Shouldn't make any difference, because the Live update performed at the end of the installation is exaclty the same as the one you run yourself but, after installing, a Windows restart might be required.

Hello,

the problem has been solved.

In order to support other users, which may have the same problem like me, these are the steps which I did:
- backup the content of personal configurations of airports, located in %appdata%/Roaming/Virtuali/GSX
- removing GSX through control panel
- manually removing all files related to virtuali (%programdata% and %appdata%) except the registry entries
- restart
- shutting down Antivirus
- download the latest version from the FSDT server
- installing GSX L2
- restart
- running (in my case P3D) the sim
It works 
- running antivirus and excluding "Addon Manager" from scanning

@ virtuali: Thank you for your support, and by the way, GSX L2 is really excellent.
