May I know the source used to download Internet Explorer 8. Please try downloading from Microsoft website. Here is the link.
Also there are Cumulative Security Update for Internet Explorer 8 for Windows XP. You may install it Here.
Hope this helps.
Thanks and Regards,
I tried to reinstall Internet Explorer 8.0 on my Windows XP computer and the program came up as MSN Explorer which wouldn't let me in. I reinstalled the software again and it now comes up as Internet Explorer, but I will not continue running.
