Loading assimp

[Eric_DD]

I am trying to use a newer version of Assimp.
I have found a assimp-vc140-mt.dll (v3.3.1) which I renamed to 
assimp.dll

When running my executable it throws a 
derelict.util.exception.SharedLibLoadException:

"Failed to load one or more shared libraries:
         assimp.dll - %1 is not a valid Win32 application.
         Assimp64.dll - The specified module could not be found"

Any idea what's going on? Are 64bit dlls not supported?
