As mentioned by GraPhiX, this error is usually caused when using Assimp64.dll in 32 bit process, or Assimp32.dll in 64 bit process. So to prevent this please check the Modules window (under Windows - Debug) when the error happens and check that there is actually Assimp64.dll loaded. If you will be using only 64 bit version of your application, then you can even remove the Assimp32.dll.
If this is correct, then check if you have the latest versions of the native assimp DLLs, AssimpNet.dll and Ab3d.PowerToys.Assimp.dll. They were distributed by the latest version and can be also downloaded from https://github.com/ab4d/Ab3d.PowerToys.W...master/lib.
If this will still not work, then maybe the error is in the native assimp importer. Try to load any model file from the Ab3d.PowerToys or Ab3d.DXEngine samples project and check if that works. If this works but your file causes the error, then you can send me the file by email so I can check it, but probably I will not be able to do much - most probably you will need to wait for the improved assimp importer (in this case you may also report an issue on its GitHub page).
