Yeah! Merry Christmas, the best Christmas present ever... and thank god for all that, only that when I installed it, it was that v1.15 still didn't work in the current (beta) Vulkan, but only on the final version of X-Plane v11.50, so I had to dial everything back to the last final update and kill the beta version... but, but I had both xEnviro AND Vulkan together and finally working.
