Here is the line from the Inno Setup script that creates the VPython 
installer for Windows:

DefaultDirName={reg:HKLM\Software\Python\PythonCore\2.0\InstallPathX,|{sd%7
d\VPython}

Translation: I'm using the registry key 
HKLM\Software\Python\PythonCore\2.0\InstallPathX,, or if this doesn't 
exist, I'm using the system drive:\VPython (typically drive C).

There doesn't seem to be a way in Inno Setup to have conditional 
statements, so I don't see a way to prompt for an installation path in case 
the correct key is not found, nor even to tell the person where the files 
are going. This is why there is a note and FAQ listed with the download. 
(Can't pick this up at the moment because the CIL server is down in 
anticipation of a planned power outage this evening.)

If someone can offer a more flexible installer builder, that would be good. 
But the current installer seems to work well for the unknowledgeble, and 
the knowledgeable should be able to cope.
