Hi,
Copy and paste the following line to the Start > Run prompt, it will
try to reinstall IE and the routine will need the XP CD.
rundll32.exe advpack.dll,LaunchINFSection %systemroot%\inf\ie.inf
Alternatively, the routine will ask for diverse files, go to a command
prompt (Start > Run > cmd) and type
dir name_of_file_needed /s (Example dir iesinfo5.ins /s)
This will tell you the location of the file, browse to that path and
click retry.
You will have to do this for 5 or 6 files, which can be bothersome.
But it can also be reinstalled without the CD.
Hope this helps
