<p>I'm sorry, but you are very unlikely to find anyone on this list
with erwin experience. pywin32 is a general purpose library that
allows talking to *any* COM object, so there are literally
hundreds and hundreds of different apps it can work with. I've
never even heard of erwin and have no idea what it does :( You
might fine someone else on this list has, and can help you, but in
the meantime...<br>
</p>
<p>You really need to find support for the erwin app, not pywin32.
Because COM works in any language, you might find the help you
need is written in terms of a language other than Python, but the
answer should translate across to Python.<br>
</p>
<p>Good luck,</p>
<p>Mark<br>
