It's not quite as clear a message as it could be, but this refers to
the installer not being able to ask Windows itself what its system
path is.  The installer isn't guessing at directories like 'Windows'
or 'WINNT' although those will be most common, nor does it scan

In order to check it uses the win32api module, which is part of the
win32 extensions package by Mark Hammond.  It sounds like you have a
Python installation but haven't installed the extensions.  Anything in
your PATH will automatically be searched for DLLs anyway, so as the
message says unless it can't find a DLL you're still ok.

You can get rid of the message by installing the win32all package,
which to be honest, is definitely worth doing on Win32 platforms.  It
comes automatically with the ActiveState Python distribution, but can
be added to any other Python installation by downloading it from
Mark's Win32 pages (

Not quite, although the root cause is the same.  In order to install
an icon resource into the resulting executable, the installer has to
use other functions from the same win32 extensions package.  So the
fact that you don't have the extensions module made the installer
(during the Configure process) turn off that capability.

Typically you'd get this sort of message if running on a Linux system,
so this lets you use a single spec file cross-platform, and it just
ignores the Windowisms (the resources) on the other platforms.
