Ugh :-(. I'm not sure what might have caused this problem, and I don't have
Windows 7. A more general web search about broken Windows registry permissions
(not specifically for Python) finds that it is not particularly uncommon.

The following *may* work around this problem:

Edit the file 'setuptools-0.6c16dev3.egg/setuptools/command/scriptsetup.py',
and delete lines 181 to 189 inclusive (starting with 'try:' and ending with
'CloseKey(target_key)'). Then try 'python setup.py build' again.
