Troubleshoot update failure windows XP Professional SP2

[Guest]

I get the following failure log for an install of Internet Explorer 7 beta.
How do I troubleshoot?

Assuming Beta IE 7 responds similarly see if this applies:

Otherwise try the appropriate beta newsgroup if you have access or uninstall
Beta IE 7.
