Update/install failure

[whoami]

I use the registered ibrowse on a Apollo Vampire Standalone V4.

It works great.

I tried updates2.5.9 and 3.0a.

When I try install, first I see.

Please insert drive "#>NIL" in any drive.

Then I see

Sorry, you need KS3.0 or higher to run IBrowse.

See attached screengrabs.
