Uninstalled successfully, rebooted, installed 2.2b2 again, making sure to turn on TortoiseBazaar (Explorer Clients or some such label) this time. This time the install failed with the same message as above. Also I have no TortoiseBzr explorer menus.
So new hypothesis: The tortoiseBazaar portion of the install is failing.
Evidence in favor: Install succeeded when I did not elect the TortoiseBazaar option.
