Problem using Python PIL/Pillow in Krypton Windows

Hi, in a new launcher addon I need to use PIL in order to automatically create fanarts/posters from DOOM levels. I use this code to include PIL:

Code:
# --- Python standard library ---
from __future__ import unicode_literals
...
from PIL import Image, ImageDraw

In Linux Debian with the packaged Kodi Krypton it works like a charm. However, in Windows I get the following error:

Code:
20:26:33.868 T:5584   ERROR: EXCEPTION Thrown (PythonToCppException) : -->Python callback/script returned the following error<--

According to this post PIL/Pillow should be available in Kodi. I have tested both Krypton 17.0 and 17.1 RC1 and both fail to load Advanced DOOM Launcher. Any ideas? Thanks a lot Smile
