That's not a particularly good method in the general case.  I don't find 
much use for the desktop icon, so I suppress it.  You might be better 
served to use the registry, in 
HKEY_LOCAL_MACHINE\Software\Python\PythonCore.  32-bit installations 
will be in HKEY_LOCAL_MACHINE\Software\WOW6432Node\Python\PythonCore (if 
you're reading from a 64-bit app).

Is it possible you have installed a 32-bit Python on a 64-bit system?  
Theoretically, you should be able to use CLSID_ShellLink from either 
one, but I'm trying to narrow things down.  Tim's code works fine for me 
with Python 3.7.2 (64 bit) on Windows 10.
