[python-win32] Trouble running profiler

[Christopher Brichford]

I get a similar errors if I use
win32com.client.gencache.EnsureDispatch instead of
win32com.client.Dispatch.  You get different error depending on the
contents of the pythonroot\lib\site-packages\win32com\gen_py\
directory.  If pythonroot\lib\site-packages\win32com\gen_py\ is empty
then you get the stack trace in the attachment error1.txt.  After you
run the test program once with or without the profiler, the
pythonroot\lib\site-packages\win32com\gen_py\ will not be empty.  When
you run the test program the second time you get the stack trace in
the attachment error2.txt

I was purposely using the dynamic version because the gencache stuff
does not work if you run python as a restricted user.  This seems to
be due to the fact that a restricted user can not make directories in
pythonroot\lib\site-packages\win32com\gen_py\...  If I were to use the
 non-dynamic code I would need a way to specify that all generated
files should be put somewhere under the user's profile.

I stopped using the Microsoft XML parser so I don't really need to use
win32com anymore.  I switch to the sgmlop parser which works fine with
the profiler.  If you are interested in continuing to work on this
issue, I'm more than happy to keep trying your suggestions.
