notized: I remove just mfc90.dll from the Pythonwin folder, and 
then do python.exe:

C:\Python26\Lib\site-packages\pythonwin>\python26\python
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 
bit (Intel)] on win32

 >>> import win32ui
 >>> win32ui.GetApp()
object 'PyCWinApp' - assoc is 00BBC728, vi=<None>, notify=0,ch/u=0/0
 >>> import dde
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: DLL load failed: Das angegebene Modul wurde nicht 
gefunden.  (module not found)
 >>>


=> dde relies on the mfc90.dll  in the same folder, but 
win32ui(.GetApp()) not !?


And: with that removed mfc90.dll I can yet start the Pythonwin.exe 
of that very same folder AND successfully import dde !:
PythonWin 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 
bit (Intel)] on win32.

 >>> import dde
 >>> os.getcwd()
'C:\\Python26\\Lib\\site-packages\\pythonwin'
 >>> dde
<module 'dde' from 'dde.pyd'>
 >>>


=> This time starting through Pythonwin.exe the same dde.pyd 
doesn't require the mfc90.dll in that folder!  (I can even remove 
the other 3 mfc dlls too)

=> There is a strange mixup of mfc DLL dependencies, varying with 
the initial .exe

There are also 2 different dates of the 4 MFC dlls here (in a very 
strange cross over order):

26.02.2011  18:43            48.640 dde.pyd
04.11.2011  11:57         1.156.600 mfc90.dll

I tried to copy various mfc90 DLL's  (4 of same date; e.g. 
18.4.2011) from WinSxS and also from pythonwin-212 to the 216 
pythonwin folder , but that still didn't solve the dde import 
problem in 216 when starting through python(w).exe

any ideas?
