Don't know the answer to your question , but this may help .
A big feature with IE5 is that
it can be repaired without uninstalling . Here is how to do it . Open
Control Panel , Add / Remove , click on Microsoft Internet Explorer ,
then click on add / remove down the bottom . This opens a window with
3 choices .
Choice 1. Add , insert your IE5 install program & you can find other
items you may not have installed 1st time .
Choice 2. Repair , fixes problems that may crop up with IE5 / Outlook
Choice 3. If unfixable , removes IE5 & goes back to IE4 , now if you
want to you can reinstall IE5 or a later version or another browser
altogether .
