Thanks, I'll look into that. Yes, I'm using 0.7.9; should I upgrade
to 0.8.0?
OK, I've tried several configurations of setup.py, and I've also
upgraded to 0.8.0. I'm still getting the same error. In case it'll
help, here's the traceback:

In "options", I set "packages" to ['sqlalchemy.dialects']. (I've also
put that in "includes", and tried ['sqlalchemy.dialects.mssql',
'sqlalchemy.dialects.mssql.pyodbc'] and got the same traceback.
I'm willing to instrument url.py to get more information, but I'm not
sure what to include. Any ideas or leads appreciated.

problem. I do a create_engine with the string

<mssql+pyodbc://%%28UserName%29s:%%28Password%29s@%%28DSN%29s>" (the
parameters are filled in using a "%" operator).
This works without a problem when I run the source code. However,
when I freeze it, I get "ArgumentError: Could not determine dialect
for 'mssql+pyodbc'." (Running on the same machine, with the same
environment.)
In case it might be relevant: I've recently moved my development
from a Windows XP machine to a Windows 7 environment on a 64-bit
machine. However, I'm using 32-bit Python, and generating 32-bit
executables.
