Couldn't start the Couatl scripting engine

[ub40]

I did all I can (uninstall /reinstall software; System restore / disable firewall, antivirus, and excluded the add-on folder  and still not able to run Couatl engine.

The problem of the programs not starting it's usually caused by one of these:

1) Defective antivirus. Download and install with the Antivirus disabled AND configure the antivirus to exclude the whole Addon Manager folder from scanning BEFORE starting the sim.

OR

2) Missing/Corrupted VC++ libraries in your system. See solution in the "Addon Manager not showing up in P3Dv4 **SOLVED**" thread:

Yes, the thread title says "P3DV4", but everything applies to FSX as well, since the libraries required by our software are the same.

I tried all that and did not work.  I had no issue since last live update.
