This is the question.
Module NOT effectively imported if I try to run script from service ( C# code) and loaded ( and script make its work)it I run it from console.
May be problem really that in this computer $env:PSModuleP differ if i run it from different processes?
Or- can it occur because code is 32bit?
It is one specific computer- in other clients ( and in my development computer -windows 7) system works. And we can not fix the problem
