2.0.0.2 to 2.0.0.3 update failure #2

Summary: 2.0.0.2 to 2.0.0.3 update failure

Comments: 
The new update fails to install other than in admin mode (Windows XP
SP2).  Now every time I start Firefox (other than admin mode), it tries
to update but fails due to lack of  privileges. Let me know how to over
come this problem.
