Works for me, I'm afraid:

 >>> keyName = "SOFTWARE\\Python\\PythonCore\\2.2\\PythonPath"
 >>> key = win32api.RegOpenKey(win32con.HKEY_LOCAL_MACHINE , keyName, 
0,win32con.KEY_ALL_ACCESS)
 >>> win32api.RegQueryValue(key, "")
'f:\\src\\python-2.2\\lib;f:\\src\\python-2.2\\pcbuild'
 >>>

Can you send a complete script that fails, using a registry key that I 
am likely to have (eg, a Python, standard windows, IE, Office etc setting)
