For every new user account the behaviour is similar, at first program runs ok but not after browsing the PythonPath.

Simple uninstalling+installing does not remove the problem, but if one deletes the Python-related registry entries for current user after uninstall, PythonWin starts again.


SOLUTION :-

Having run out of ideas, I changed the name of scintilla.dll to scintilla.dll.hold and ran Pythonwin.exe. It generated some errors, but didn't fail to open. It wouldn't open any files due to the lack of scintilla.dll.

However, when I subsequently renamed scintilla.dll.hold back to scintilla.dll - pythonwin started working again.
