Couatl does not install properly in Prepar3Dv4

[medeo04]

Hello,

I am running Prepar3dvn4.5 with FSDT Universal installer vn 1.1.5, GSX vn 2.9.8
After running the installer , when I then want to start Prepar3D I get an error message from Couatl64_P3d.exe , see screenshot in this link:

Do you have any advice how to correct this? None of my FSDT airports now work.


PS: I had disabled my AV program during the Installation


Thanks,
Michael.

Is that Windows 7 ?

Yes, still on Windows 7. Until I updated Couatl via Live Update a few weeks ago all airports worked fine. I cannot remember what the (working) version of Couatl was.

This is the only support we can offer about Windows 7:

As explained there, if it worked back then or until now, there's no guarantee it will always work, since any update to the C++ runtimes libraries by Microsoft that we MUST use to be sure everything is working on currently supported OS, might break compatibility with unsupported OS at any time, and there's nothing we can do to prevent that.
