Python Dll import Error

I am importing 5 dll’s into a python node but one is causing a Errno 2 issue(see below image), this error effects dynamo 0.8.2/0.9.0 and 2015 and 2016 versions of the dll. I have a sneaky feeling it is the dll that is a issue but thought i would post here in case someone has got it working. dll is also from civil 3d vanilla install and I followed instructions from ADN for which civil 3d dll’s that are needed.
