DLL load failed - cx_freeze

[JonasR-]

I get the following stacktrace when I try to start a program using the 3.0.1 psutil library.
The program is packed using cx_freeze on a Windows 7 machine and gets executed on a Windows XP machine.
The problem does not occur on psutil 2.2.1

Traceback (most recent call last):
  File "C:\Python27\lib\site-packages\cx_Freeze\initscripts\Console.py", line 27, in <module>
  File "main.py", line 6, in <module>

Not sure how to reproduce this. Does the problem occur if you install psutil from scratch on Windows XP (either via pip or by installing the exe)?

Thanks for your response
Yes this also happens on my freshly installed Python 2.7.10 with psutil 3.0.1. Its the same Windows XP system and psutil was installed with "psutil-3.0.1.win32-py2.7.exe".
The traceback looks a bit different but I think it cohere

ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.

By the way the translation for "Die angegebene Prozedur wurde nicht gefunden." is "The specified procedure could not be found"

Looks like msvcr90.dll is missing. Thats strange because Microsoft Visual C++ 2008 Redist and SP1 of it are installed.

I haven't tried 3.0.1 yet but it might be related to the inet_ntop issue I saw earlier.

@JonasR- Have you tried copying the msvcr90.dll to the same directory as the python app?

[JonasR-]

Sorry for the late response.
Also with the dll copied to the working dir I got no change.
"Dependency Walker" sayes it gets found

I can confirm the same error on WinXP with Python 2.7.10 and psutil 3.0.1 and psutil 3.0.0.

I just did some testing with the zipped release of 3.0.1 and it's definitely due to the issue identified in #616 . I'll work on that patch to get it working across WinXP / Win 7.
