I got some errors from last Blender 3D version 2.78 windows 64b.
I try to install over older Blender 3D version 2.78 RC2 windows 64b.
First come with SDL lib error . I used repair and .msi .
When the Blender 3D - version 2.78 windows 64b starts come with this under command line:
Read new prefs: C:\Users\GeorgeCatalin\AppData\Roaming\Blender Foundation\Blender\2.78\config\userpref.blend
AL lib: (EE) UpdateDeviceParams: Failed to set 48000hz, got 44100hz instead
found bundled python: C:\Program Files\Blender Foundation\Blender\2.78\python

addon not found: 'makeclothes'
addon not found: 'io_import_scene_mhx'

Seem don’t see my old addons but know was into last Blender 3D.
Maybe some users have same problems…
