If you are referring to the known VCRUNTIME crash caused by the standard Simconnect menu which affects every app that uses a menu, there's just nothing we can do on our side to fix it, but we are sure LM will fix in the next update.
However, now the Couatl engine is a 64 bit app compiled with the P3D Simconnect, it should work better in general and have less dependencies on older runtimes used by the FSX version.
