Natron-2.3.15-Win7-quickfix1.zip (3.2 MB)
Completely untested as I don’t have Windows 7 available anymore, but I did use the same patch as last time, so it should work (in theory 
). Remember to clear the plugin cache in Natron or else the IO plugins might not load. Also remember to set your locale accordingly, and as a final note: this is unofficial and unsupported.
