I still can't seem to get this to work correctly. Here is the code I am testing with: --- import win32com.client from win32com.client import gencache, Dispatch import os, sys from win32com.shell import shell import win32com.client.dynamic print "Creating late-bound Optix object" xl = win32com.client.dynamic.Dispatch("Optix.Application") print "The Optix object is", `xl` gencache.EnsureModule('{4BD66BC4-4AA0-11CF-A13A-00A024140CAD}', 0, 1, 2) optix = Dispatch("Optix.Application") print optix sys.exit(0) --- The output is: Creating late-bound Optix object The Optix object is The actual above gencache statement was not copied from the makepy utility as it could not find Optix.Application (or the classid) so I just ran it on another object and replaced it's classid with Optix's classid. I have noticed that Optix.Application is not in the TypeLib list inside of makepy utility though it does show up under all onjects in MS's OLE Browser. Another odd thing is that I can use Optix.Application in python (to some degree) but can't use it for what I need sense makepy/gencache doesn't seem to make anything.
