[Visualpython-users] ImportError: DLL load failed: %1 isn't an available win32 application.

[ptrottant <p.t...@fr...>]

Hello,

 

I'm trying to make run an old script using vpython (which works fine for
years).

I'm now on windows 7 64bit, I installed VPython-Win-Py2.7-5.72.exe in
c:\python27 which is the place for python 2.7 on my computer.

(notice that the installation process alert me about the fact it didn't find
python 2.7 installation directory. As requested I gave it the place).

Unfortunately it seems to have trouble with cvisual :

 

Traceback (most recent call last):

  File "C:\3S\myprog23\pression3.py", line 3, in <module>

    import visual

  File "C:\Python27\lib\site-packages\visual\__init__.py", line 1, in
<module>

    from .visual_all import *

  File "C:\Python27\lib\site-packages\visual\visual_all.py", line 1, in
<module>

    from vis import version

  File "C:\Python27\lib\site-packages\vis\__init__.py", line 3, in <module>

    from .cvisual import (vector, dot, mag, mag2, norm, cross, rotate, comp,
proj, diff_angle, rate, waitclose)

ImportError: DLL load failed: %1 n'est pas une application Win32 valide.
(translated by is not a valid Win32 application)

 

I found only a cvisual.pyd file in the c:\python27\Lib\site-packages\vis
directory

 

So, I will be very pleased if someone could help me.

 

Thanks for your support. Don't hesitate if you want any other information or
test result.

 

Regards.

It sounds like you have a 64-bit version of Python 2.7 installed. As
it says on the Windows download page at vpython.org:

First, download and install Python-2.7.1 (Important: Let it install in
C:\Python27)(There is not a VPython version for Windows 64-bit Python,
but this 32-bit version of Python works fine on 64-bit Windows
machines)
