With many, many thanks to Barry Scott, a new release of the Win32 Installer package is here: http://www.mcmillan-inc.com/install1.html Barry found my major boo-boo in the code that resolves a C extension inside a package. He also greatly improved the messages that come out of the runtime when something goes wrong at the top level. And if you're a user of Mark Hammond's stuff, he also made it so, for example, "import pywintypes" automatically finds PyWinTypes20.dll. Also in this release: the fix for builtin modules, and a fix to the analysis of C extensions and dlls. The documentation now has a page of how-tos for common extensions / packages (e.g., Pmw, PIL among others). Background: The Win32 Installer is a sort of compilerless Freeze - a way of distributing Python apps with all the required support built in. It also understands binary resources (.dlls and .pyds) and can package up arbitrary files that your app might require. Old-Python-style license.
