AIS_Trihedron Exception on comps without OCC

Dear All:

I have a problem using AIS_Trihedron in my application. If i run my program on computers where OCC is not installed an exception occures

************** Exception Text **************
System.Runtime.InteropServices.SEHException: External component has thrown an exception.
at AIS_Trihedron.__ctor(AIS_Trihedron* , Handle_Geom_Axis2Placement* )
at OCCInteractiveManager.CreateTrihedron(OCCInteractiveManager* ) in d:\my documents\visual studio projects\cncwood\gcshell\occinteractivemanager.cpp:line 54
at GCShell.InitOCCInteractiveManager() in d:\my documents\visual studio projects\cncwood\gcshell\gcshell.h:line 158

After this if i choose continue i can use all my functions (import/export STEP, selection ets)
Could you tell me how to resolve this problem
PS All dlls are added to root folder of my application
