I forgot to add that Spyder, QtDesigner, Mayavi 2 etc. can be started from the 
commandline without problem. It is (only?) the xyhome.pyw that does not run.

Uninstall, delete  HKLM/Wow6432Node/Software/Python(x,y) and re-install.

Please report the outcome.

Hi,

- uninstalled Python(x,y)
- removed the directory "C:\Python27" by Hand
- in "regedt32", eliminated all references to "Python(x,y)" (Note: The
"HKeyLocalMachine/Software/Python(x,y)" was removed by the
in-installation; and I did not find anything under HKLM that I could
associate with "Wow6432")
- Reinstalled Python(x,y) 2.7.2.2.rc1
- The same problem appeared again.

Let me know if I should try anything else.

Can you please check under HKCU/Software/Python(x,y)

From the command line:
reg query HKCU\Software\Python(x,y)

If the above lists anything, delete the HKCU\Software\Python(x,y).

I have downloaded the new released Pyhton(x,y) 2.7.2.2, and tried to install 
it. The same problem appeared.
The command 
reg query HKCU\Software\Python(x,y)
produces no response, and there is NO entry under HKCY\Software\Python(x,y).
Note that this comment now related to the released version, NOT to the RC1.

I also tried to install it on a 64bit Win7 machine. There the "xyhome.pyw" 
elicits no response (no Python(x,y) window is started). It seems as if the 
Qt-Designer Interface does not come up (while other Qt-Designer applications 
that I have written run ok).
Is there any way that I can help you to debug that problem?

I've actually managed to reproduce the symptoms.

Please make sure that 
C:\Python27\Lib\site-packages\PyQt4
is the _first_ entry in your PATH environment variable.

from the command shell:
SET PATH=C:\Python27\Lib\site-packages\PyQt4;%PATH%
python c:\Python27\Scripts\xyhome.pyw

Wow, I am REALLY impressed: 
a) by the speed of your response, and
b) that you figured out the problem.
Your suggestion fixed both, the 32bit and the 64bit system.
I start to feel indebted: let me know how I can assist you with furthering the 
development of Python(x,y).
Thanks - thomas
