SQL 2005 installation error

Hi, has anyone experienced this error before?
"An unhandled win32 execution occured in msiexec.exe[3016]. Just-In_Time debugging this exception
failed with the following error. No installed debugger has Just-In_Time debugging enabled. In Visual
Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In_time.
Check the documentation index for 'Just_In-Time debugging errors' for more information."
System: Win XP-Pro
I've run various registry cleaners, uninstallers, etc. Not nothing seems to help. There was not much information on this error on the net that I could find.
Thanks,
EJM.

Do you have sp2 for xp installed?
