You can also try fixing IE through your add/remove in control panel, once you select IE which ever version your using, 3 options will be shown choose fix IE, a reboot is also required.
If the none of the previous answers worked, obtain the latest version of Internet Explorer compatable with your operating system and start from scratch with a new installation. If you have the option to un-install/overwrite any previous versions, DOIT! Options to "Fix or Repair have never worked for me". Does the error message display a .dll error message related to mshtml32.dll or a similar one?
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.
