Using an earlier version of Internet Explorer in Windows 98 SE

IE 6 simply does not work in Windows 98 SE. There is just an error message: “Buffer overrun.”

In association with this problem Outlook Express 6 will receive mail but cannot send it.

The question. As it is impossible to uninstal IE 6, would it be OK to install an earlier version (5 or 5.5) in a separate folder?

A problem might be that AOL functions perfectly with its own connection to IE 6.

Please do not suggest that I download ieradicator because I have done that previously and it DOES NOT WORK.
