do you use proxy in  your network? like ISA firewall?
go to control pannel.

open liveupdate; enter the proxy settings


open liveupate make it interactive



type luall.exe

try downloading smaller components; seems like u r firwall is blocking it....

Please check this:

"LU1863: Insufficient free disk space" occurs when attempting to run LiveUpdate, even with adequate available disk space.
Also, please check the Following:
  • Ensure that you are able to "ping"
  • Use "tracert" on the LiveUpdate server, to see how long it takes to reach the server
  • Ensure that the proxy settings are configured properly.
  • Uninstall and reinstall the LiveUpdate component

Also check if you can Use a web browser to visit and give the web filtering software permission. Run LiveUpdate again.

Hope the above steps are of some help!!!
