Hi,
When you get an error message, click on Details. Which DLLs are mentioned?
Also, from IE> Tools> Manage add-ons, disable any non-Microsoft add-ons to
see if one of them is the culprit.
A very thorough search for malware is in order.
You will want to run Ad-aware, Spybot and MS Anti-Spyware (Beta.) All
programs should be updated before use.

Or...
A legitimate program running in the background may be causing this. Disable
(for diagnostic purposes) programs such as pop-up blockers, security,
toolbars and other add-ons for IE, anti-virus, etc. Take a look at any
program that might be interfering with IE. You may have to reinstall, or not
reinstall, a program.
