dll problem with Python

Hi all....

Hope this isn't as baffling to some of you out there as it is to me....I'm trying to run a Python script and when its run in pythonWin it throws the error "The program cant start because ProductionSolutionEngineLib.dll is missing. Ive tried reinstalling PythonWin and that hasnt solved it. I'm wondering if anyone has had simmilar issues?

Thank you for reading this and for any help you may have.
