After you uninstall Internet Explorer 5.01 to return to your previous Internet Explorer 5.0 installation, the Microsoft Internet Explorer 5 and Internet Tools entry may be missing from the list of installed programs in the Add/Remove Programs tool.
This behavior can occur if the removal of Internet Explorer 5.01 removed the previous uninstallation information from the registry.
To work around this issue, reinstall Internet Explorer 5.0.
NOTE: You can also choose to repair Internet Explorer 5.0 without the user interface.
