The Application cannot locate win32ui.pyd (or Python) (126)

[vsoler]

Hi all,

I just installed python 3.1.2 where I used to have python 2.6.4. I'm
working on Win7.

The IDLE GUI works, but I get the following message when trying to
open *.py files written for py 2.6

The Application cannot locate win32ui.pyd (or Python) (126)

Should I change the PATH in Windows? Should I change the PYTHONPATH? I
am a bit lost. Everything worked fine with 2.6.

Moreover, when I try to open an old *.py file, I sometimes get a
message saying that the file should be converted to UTF-8. What does
this mean?

I'm also trying to use the 2to3 converter, but I cannot see where the
converted files are written to!

Any help is highly appreciated.

win32ui is part of the PyWin32 package. Most likely you have a version
of PyWin32 for Python 2.6 installed, you should uninstall that and
install PyWin32 for Python 3.1. Downloads are at
http://sourceforge.net/projects/pywin32/files/

You should do the same for any other third party packages that are
installed.

Moreover, when I try to open an old *.py file, I sometimes get a
message saying that the file should be converted to UTF-8. What does
this mean?

Those files contain non-ascii characters (e.g. £, €, æ). Non-ascii
characters must be encoded when saved using and encoding. UTF-8 is one
such encoding, and it was chosen as the default .py encoding for
Python 3.x. Those files are probably in iso8859, cp432, or perhaps
UTF-16 (aka UCS-2). You can save them in UTF-8 using your favourite
text editor, or declare the encoding so Python 3 knows it. More info:

I think 2to3 prints a diff of the file changes to the console. The -w
command line option should modify files in place.

Thank you Alex for your detailes reply.

Before switching to Python 3.1.2 I removed all my Python 2.6 packages
(python, pywin32, numpy, wxpython). However, the removal was not
complete since some files could not be removed. Additionally, I still
see my C:\python26 directory which is suposed not to exist any longer.

If I go to the Control Panel, I cannot see any of the above suposedly
removed programs as pending of removal, so I really do not know what
more to do. I was even thinking of removing the C:\python26 directory
with the Supr key, but I always heard that it is not a good idea, the
Registry could become inconsistent. Additionally, I have not found in
my Win7 system nay utility for fixing it, should it become corrupt.

Perhaps my questions concern a bit more the Operating system (windows)
than they do python, but since I am fond of python and I definitely
would like to become somehow proficient at it, I would like to solve
the problem that I have.

I would not like to take a lot of your time, but, do you have any
hints as to what I should do to 'tune' my PC?

Thank you very much for your help.

It probably contains one or two files the installers weren't aware of.
E.g. a module you added manually, a log, a .pyc

Take a backup then either delete the Python26 directory, or rename it.
Any problems, reverse the process.
