Using v2.77a Should I go for a clean install? That is all I can think of doing.

    $\begingroup$ This isn't an issue with Blender, you might be best to report this to the add-on author. $\endgroup$ – ideasman42 May 3 '16 at 12:02

    $\begingroup$ This is Blender not able to install an add-on or use an add-on properly. I'd say it is a issue with Blender. $\endgroup$ – Eric Huelin May 3 '16 at 12:44

    $\begingroup$ Whatever the case, the missing module is not part of Blender, so this isnt a problem with Blender. $\endgroup$ – ideasman42 May 3 '16 at 13:29

From the error message it seems that you are using the BOS FBX importer with Blender 2.77.

The newest version of this add-on (at the time of this post) relies on precompiled libraries for Python 3.4 (see scripts/addons/io_scene_bos_fbx/win64bit/python34/UMIO.pyd) but Blender 2.77 ships with Python 3.5, so it won't be able to find the UMIO module.

Name                          Version
Blender 2.76                  Python 3.4
Blender 2.77                  Python 3.5
Blender 2.78                  Python 3.5

BOS FBX Importer 2015-07-04   Python 3.4

You need to either keep around a copy of Blender 2.76 to use this add-on with or ask the author to provide a newer version for Python 3.5.


In file %APPDATA%\Roaming\Blender Foundation\Blender\2.78\scripts\addons\io_scene_bos_fbx\import_bos_fbx.py

Add these code under um_folder = os.path.join(um_folder, "win64bit") and um_folder = os.path.join(um_folder, "win32bit") :

if sys.version_info[:2] == (3, 5): um_folder = os.path.join(um_folder, "python34")

This should be a temporary method to solve the problem.
