Summary: Windows installer start menu registry

Initial Comment:
The new installer for Windows Python 2.2b1 enters a 
long string into the InstallGroup portion of the 
registry:

"C:\WINDOWS\StartMenu\Programs\Python 2.2"

Previous Windows installers entered a short string:

"Python 2.1"

I believe the long string is incorrect and the short 
string correct. For example, when I try to use the 
freeware installer InnoSetup (plus extensions) to 
create an installer for VPython, an incorrect start 
menu address is generated when I attempt to install a 
on the start menu a pointer to the idlefork version of 
IDLE. This worked fine in the past, with the short 
form registry item.

Sorry; I thought "InstallGroup" was adequate ID. It's in 
HKEY_LOCAL_MACHINE, Python, PythonCore, 2.2, InstallPath, 
InstallGroup.

>From your explanation, I see that this is a feature, not a 
bug. The rule then is that starting with Python 2.2, the 
InstallGroup entry will be the full path name to the 
location of the start menu entry rather than simply "Python 
N.N" as it was in the past. I just need to change my own 
installer to expect the full path name in the future. I 
made the wrong guess in calling it "incorrect" -- it's just 
different, not incorrect. Thanks.

Exactly which key are you talking about?  Please give a 
full path, starting with the hive (HKLM or HKCU or 
HKCR?).  "The InstallGroup portion of the registry" doesn't 
mean much to me, so unless you spell it out I can only 
guess.

Wise did change how they define their internal %GROUP% vrbl 
between versions 5.0a (used for pre-2.2 installers) and 
8.14 (used for 2.2), and in the way you describe.  This is 
used for several purposes, though, and some clearly need 
the full path.

As to correct vs incorrect, beats me -- Python sets some 
registry entries common to all Windows programs, 
and "correct" for them means they work the way MS says they 
should; I don't know of any we get wrong in that sense.  
Other registry entries are unique to Python, and since 
neither Windows nor Python ever looks at them, I don't know 
why we even set them up (beyond that, AFAIK, we always 
have).
