Hi Tim and all,
Thanks for your reply... I thought would be helpful looking at the error code
from win32, I got.
Basically, I'm getting error in the _init_.py line 85, 95, 108 and 245. See
below.
I got this error in all programs I try to implement win32com.client module.
I'm quite new Python user and I will appreciate your kind further help.
Best Regards,
Michel

Are you on a 64-bit operating system? Are you entirely sure that the Bloomberg
Desktop API v3 a 32-bit service? Remember that you can ONLY call a 32-bit
in-process server from a 32-bit application, and a 64-bit server from a 64-bit
application.
You could check in the registry. If you find an entry under
HKEY_CLASSES_ROOT\blpcomapi.Session.1
then you have a 64-bit version. If you find an entry under
HKEY_CLASSES_ROOT\Wow6432Node\blpcomapi.Session.1
then you have a 32-bit version.
