Agree with hilowe, IE is essential for the system,
Normally no matter how hard you try, you are never able to delete IE compeletely from your compter .
search your computer for Internet Explorer, it should still be there
(programe files\Internet Explorer)
If you did delete IE, here is one way you can try:
enter Control Panel->Add/Remove Programes->Add/Remove components(On the left)->select Internet Explorer
Insert your Dics if necessary, Good luck
