This is a continuation of bug 4423, now that Mike's patch
fixes the msi problem.
The official registration/download URL for Maya PLE is

Maya's installer crashes after putting up an initial dialog.

The log is interesting - the call stack is kind of deep.
Maybe some message is being handled synchronously when
it should be deferred.  I'll attach the log.
