[UE 4.11.2] System environment variables ignored?

It seems to me that the system environment variables (like PATH, …) are reset for UE process, when I launch my project (either from VS or Epic launcher).
If thats the case, i would like to ask if its possible to avoid this behaviour or at least force own environment.
Core of my problem is loading system-wide dynamic libraries (dlls), which are exposed throught path in system PATH env. variable (EU won’t find them).

See my post on this here
