I tried to set _MEIPASS2 to
os.path.dirname(os.path.abspath(sys.executable)) and it seems to work
correctly.
Attached is the multiprocess code that works for me on winxp without any
context error. Could you test it please?
If it works we should create from this example a test case for
pyinstaller.
Output when running on winxp:
