Can not find and load the system DllName registry entry for {7B849a69-220F-451E-B3FE-2CB811AF94AE}. Probable error of registration.

Solution: Lately the error above is present on your system after you uninstall Internet Explorer 8.
Indeed IE8 will not uninstall correctly, and some classes remain in the system log, then to correct the error should go to Start - Regedit - Enter and delete the classes indicated in the braces in your error message.
