BLAM doesnt work in Blender 2.77

Hi. I need BLAM to track image, but it doesn t work in Blender 2.77. How to activate it? It says some errors in Windows 10 Pro x64.

Problably BLAM doesn´t work in the 2.77, because the new Blender comes with python 3.5 so maybe it is needed to update the script. In the meantime you can always install a previous Blender version in another folder and use BLAM there.

BLAM camera calibration works fine on 2.77 on OSX. Maybe you have to upgrade Python.
I have not checked the other features though.

Yep works correct with OS X.

Can you post the Win10 error message please?
