Hi
I am building a 32-bit C++ application using Visual C++ Express 2008
on 64-bit Windows 7. The application links to Python, so I
installed 32-bit Python 2.7.2 by running python-2.7.2.msi.
When I run my app, I get error:
... python27.dll is missing from your computer ...
and, indeed, it is in neither C:\Windows\System32 nor C:\Windows\SysWOW64.
Please will someone suggest what I am doing wrong?
Maybe nothing, maybe something, too little information to know.
First, _look_ for the file. That is, find the file wherever it
is. Go to the command line and do
dir /s \ >allfiles.20110617a
Then look at that listing. WIth Python 2.7.2 which I just installed
the dll ends up in SysWOW64. And now I see that they are all there,
and nowhere else!
Directory of C:\Windows\SysWOW64

02/20/2011 10:29 PM 2,227,712 python32.dll
But in December they were in both places!

(Maybe something to do with the 32-bit vs. 64-bit installs
mis-direction? I use only the 32-bit now...)
Now, do another install of Python 2.7.2 on another machine. Do a
file listing. Where do the DLLs end up? Re-do the install on your
machine. Where do the DLLs end up?
Do some more checking and tell us what you've _found_ and where...
Best regards
