GSX Couatl scripting engine hasn't started **SOLVED**

[Neal]

I installed GSX Pro and now I'm getting errors, another SODED is running in the background and crashing FSX.
I re-installed practically everything and now I'm missing files could you please tell me where to find it and re-install them

Thanks

Hi Umberto, you might want to check the Coautl code that fetches the plan from Simbrief and add an exception in the case a file plan doesn't exist.

Coautl kept crashing for me after updating to the latest version using the offline installer, but after enabling the log, I deduced the culprit was that I didn't have a flight plan filed in Simbrief before loading the aircraft (I wasn't logged in at all in Simbrief... I hadn't used the PC for a month or so).

It was an endless loop that kept crashing Coautl without any clue. This is in P3D (v5.3 HF2).  So, maybe an exception to avoid the crash might help!

Hope this helps

Already done, already on Live Update.

My Coutal Engine will not start. I get the following message:C:\ Program Files (x86) Addon Manager\coutal64\Coutal64_MSFA.exe It then states The file or directory is corrupted or unreadable Noye that the fsdt Live Update and Installer both work. The problem is that when in MSFS and I try to use the GSX it states Coutal Engine has not started. How can I resolve this problem as GSX Pro is non functional

You are posting it in the FSX/P3D section.

They don't care, they just mark as solved

I don't know what you are trying to say here, you are replying to a very old post  that yes, of course it's solved. Are YOU still having the SAME issue ? If yes, provide a report and we'll see if it's really the same issue.

Please tell me what happened? Everything worked fine before!

Your error looks similar to the one discussed here:

https://www.fsdreamteam.com/forum/index.php/topic,33282.msg209440.html#msg209440

So, check your livery file, maybe it has the same problem.

I opened the aircraft.cfg file with a 16-bit editor. Everything is displayed correctly there. But I still changed it to "" but the problem remains. It gives an error. And this problem is on all planes. Today I did an update and nothing helps.

I'm sorry, but you log doesn't show anything other then a generic inability to connect to the sim, suggesting a sim installation issue. A tested FSX with the version you have (5770), which is the latest one, so it seem you are fully updated, and it works normally.
