preform is 32 bit as I can see, you can use proboably 2GB of RAM although you have 16GB. Try using WIN 64x or easy way is to open your stl file in some 3D modeling program and optimize polygon count (less polygons), you have probably too much polygons on your model and not “enough” memory.
I’m running Windows Version 10.0.15063 Build 15063 Pro, 64-bit,
I’ll try messing with the .stl in meshmixer and see if that helps (as suggested by Robert Koch in my support ticket).
