When I reformatted my hard drive the other day, I didn't think installing pythonwin would be such a hassle, but it was.
Apparently Microsoft has deprecated some libraries in later versions of its dot NET framework. In order to solve the missing dll problem that you might encounter, go here: http://starship.python.net/crew/mhammond/win32
and download the dlls posted on this site. Place them in the ..\windows\system32 directory.
Pythonwin should now work.
