Ok, just testing, I uninstalled blenderfbx-2.77, and then installed BL_20150704.
When I clicked the import button, I get this error message:
I then uninstalled BL_20150704, and reinstalled blenderfbx-2.77.
When I clicked the import button, the console didn't produce any error messages. It's like the addon never initialized.
To be clear, with each addon installation, I saw a green message above saying the module was successfully installed: i.imgur.com/YxBF7Xw.png
But apparently both addons don't import anything, and only 1 of them produced the error message above.
I was wondering if the download link on the page is the wrong one.
I'm using 64bit Windows.
I'm using Blender 2.79b .zip install instead of .msi
I have the native FBX Importer addon disabled.
umconv_bos_fbx2017_win64.exe has admin privilege.
umconv_bos_fbx2017_win64.exe is installed in the same location as Blender.exe.
