Hi,
First of all thanks for your answer :). But after updated my *IRONPYTHONPATH
* as follow:
set IRONPYTHONPATH=c:\Python27\Lib
I get this error:
-----------------------------------------
c:\temp>ipy test-ipy-multiprocessing.py
Traceback (most recent call last):
  File "test-ipy-multiprocessing.py", line 1, in <module>
  File "c:\Python27\Lib\multiprocessing\__init__.py", line 63, in <module>
  File "c:\Python27\Lib\multiprocessing\process.py", line 286, in <module>
  File "c:\Python27\Lib\multiprocessing\process.py", line 283, in __init__
TypeError: expected IList[Byte], got str
-----------------------------------------
