[python-win32] ImportError: DLL load failed: The specified procedure could not be found.

[Liu, Donald (H USA)]

Hi Mark,

Thanks for your reply.  I ran "dir c:\Windows\system32\py*.dll", and got
the following:

C:\>dir Windows\system32\py*.dll
 Volume in drive C is System
 Volume Serial Number is F8F2-995F

 Directory of C:\Windows\system32

03/27/2008  06:12 PM         2,117,632 python25.dll
03/27/2008  06:13 PM           323,584 pythoncom25.dll
03/27/2008  06:13 PM            98,304 pywintypes25.dll
               3 File(s)      2,539,520 bytes
               0 Dir(s)  12,925,677,568 bytes free

Looks like there's only one set of these files in the system32
directory.

By the way, I only had problem with installation on the PC at work.  My
PC at home, which also has Windows XP, runs ActivePython with no
problem.  Unfortunately it's the PC at work that I'd like to make the
installation work ...

Thanks again,
Donald

Check if you have copies of pywintypes25.dll and pythoncom25.dll in your

system32 directory, and if so, that they are identical to the ones in 
your Python directory.  If they are not, update the system32 ones with 
the python ones.

Cheers,

Mark
