Fresh P3D V4.2 Installation - GSX Couatl Error **SOLVED**
« on: May 28, 2018, 08:31:11 pm »
I'm not sure when it happened, but a recent Live Update of GSX seems to be causing a Couatl Script Error every time I startup Prepar3D v4.2.
I've had GSX running well for years, but suddenly it's become a problem.

I've checked the forums, and tried several things, such as un-installing and re-installing GSX (using the latest version 2.3.0.3), as well as loading
every possible Microsoft Visual C++ Redistributables (2005, 2008, 2010, 2012, 2013, 2015, 2017).

My last ditch effort was to go back to a fresh Windows 10 Pro Install running all the updates; and only install P3Dv 4.2 and GSX, and nothing more.
Still, the error is occurring.

I've attached a screen capture of the message, as well as the Couatl.err file.  Can someone confirm what the issue is?  Below is the error:

I cannot reproduce this and nobody else has reported it. And, since I just got a new PC today, I had the chance to install P3D and GSX on a freshly installed Windows 10 and, of course, no problems whatsoever.

The only thing I can say, since that's an error inside a Python graphic library, it MIGHT be related to video card drivers. Try downloading the latest drivers, and make a fresh install of them with all default settings.

Greatly appreciate the quick reply!  You provided the clue that I needed, which had something to do with the graphics card.
I couldn't tell what the Traceback was referring to, and if there was ANY indication that it was a graphics issue, I would've
immediately looked in that direction.  The only thing that I could grasp from that error log was some possibility that it
was an access rights issue to a directory possibly?

I ended up doing a clean install, and used the driver that Windows 10 provides, which is for an ATI Radeon RX480 Video Card.
That did the trick, as it works with no issues!

Once again, greatly appreciate both the quick reply, and the clue that it had to do with the graphics card.
