Hi Tim, 

Hmmm, I may have to play with _winreg, is is new with Python 2.4?

Anyway, from the _winreg docs - 

 *EnumValue*( key, index) Enumerates values of an open registry key, 
returning a tuple. 

key is an already open key, or any one of the predefined HKEY_* constants. 

index is an integer that identifies the index of the value to retrieve. 

The function retrieves the name of one subkey each time it is called. It is 
typically called repeatedly, until an EnvironmentError exception is raised, 
indicating no more values.

There's your issue - 
E_key = 
The second value needs to be an integer that is an index.
Typical usage would look like this - 
 i = 0
regKeys = []
while 1:
regKeys.append(_winreg.EnumValue(key, i))
i += 1
except EnvironmentError:

Good luck, 

Liam Clarke
