I also tried this in Phyton Console within FreeCAD but con't figure out what is the problem.
>>> import ctypes
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Program Files\FME\python\python27\lib\ctypes\__init__.py", line 10, in <module>
from _ctypes import Union, Structure, Array
ImportError: No module named _ctypes

My installer: FreeCAD.0.16.6706.f86a4e4-WIN-x86-installer.exe

I am new to FreeCAD. Please help.

I do not know where the problem is but if you would like to work with FEM workbench it is really recommended to use the latest development version 0.17.xxxx from https://github.com/FreeCAD/FreeCAD/releases. FreeCAD FEM has had dozens of bugfixes and changes since 0.16.6706

ImportError: No module named _ctypes

Your FreeCAD installation lacks of the Python module _ctypes.pyd. You can check a newer installer if it's now added or in case you have a Python2.7 installation copy it from there.

You can check a newer installer

I just downloaded the installer referenced by HP Lim and the _ctypes.pyd is there. If I rename it and start FreeCAD I get the import erro and in report view.

Code: Select all

    import ctypes
  File "C:\Program Files (x86)\FreeCAD 0.16\bin\lib\ctypes\__init__.py", line 10, in <module>
    from _ctypes import Union, Structure, Array

File "C:\Program Files\FME\python\python27\lib\ctypes\__init__.py", line 10, in <module>

In HP Lim's case it looks like a system installed Python is being used
@HP Lim what python version is listed at the top of the python console?
