True, and the changes to path and pythonpath are gone after I close the console window, but the results of the assoc and ftype commands are changes to the registry that linger. If I run my setup on a computer that has python installed, I will overwrite the pre-existing registry settings. I can restore them with a script, but I can't guarantee that my restore script will run. I'm still looking for a way to modify these temporarily, but it looks like I might be "up the creek" on this one. Oh well. Thanks again, CJL -- http://mail.python.org/mailman/listinfo/python-list
