Add-On builder: migration tool error on windows

[flobishop]

Hi, I have the following error when I try to run project_migration_tool on windows:
C:\Program Files\Splunk\etc\apps\splunk_app_addon-builder\bin\aob\aob_tools>project_migration_tool.bat
PYTHONPATH=C:\dev\splunk-sdk-python-1.6.6;C:\Program Files\Splunk\etc\apps\splunk_app_addon-builder\bin\aob;C:\Program Files\Splunk\etc\apps\splunk_app_addon-builder\bin\aob\aob_tool
Traceback (most recent call last):
File "project_migration_tool.py", line 16, in
import aob.aob_tools
ImportError: No module named aob.aob_tools

Any idea ?
