Microsoft Internet Explorer error message

Clarifications

Since re-installing IE6 involves a XP repair install, which can be a hassle, try this first:
With Internet Explorer open, click on the Tools menu and select Internet Options. There, click on the Advanced tab and then the Restore Defaults button. Lastly, click Apply and OK. Close & Reopen IE and test.

If the issue continues, download and install the latest version of Sun Java Runtime:

Another possibility is there may be an add-on that is causing problems. In IE, go to Tools and select Manage Add-Ons. Here you can disable questionable Add-Ons and/or update their ActiveX components.

If the issue still continues, your situation may be due to Spyware, Adware or Malware.
Start by emptying your Internet Cache*.

Were you able to resolve your issue?
If So, what was the fix?

It is very likely that the cause of the error with the internet explorer (that is just another application like many in windows) error is a faulty registry setting. I would consider using a RegistryCleaner to attempt to fix the error....
