This error means that the assembly wasn't found on your computer.

which assembly do you mean? the main assembly or direct assembly of windows?
is there any tutorial on how can protect only dll files or any customer use your software for protecting nt8 add on ?

I mean the assembly that you see in the error message (SharpDX.Direct2D1).
