Error 0x40000015 .net framework 1.1 service pack

[JKeith]

Error message 0x40000015 when windows update tries to install .net framework
1.1 service pack 1 (KB886903). Error message is from visual c++ runtime lib
and refers to temp/SLD.tmp file and that application has requested that
runtime terminate in an unusual way. Have been thru the KB article
referenced with the service pack and followed all recommended steps without
luck. Info was dated several months ago though. Any help will be
appreciated.

I should also say that my system is XP/Pro SP2 with all other current updates
installed.
Thanks.
