No module named lib.commands

[Johannes]

Hi everyone,

I just downloaded the bazaar standalone installer (v2.0.4-2),
ran it with
"install everything" settings,
got no error messages and restarted my computer
when prompted.

When I enter "bzr init" in a command prompt, I get the following message:

No module named lib.commands
Unable to load plugin u'explorer' from u'C:/Program Files/Bazaar/plugins'

The .bzr.log file contains this:

I'm running on Vista Home Premium SP1. Is this a known issue?
Thanks for your help.
