Alan, I have a USB DVD drive you cound borrow if required, depending on where you live.
I’m back to La Palma on Friday, all being well, so logistics might be a problem but surely a solveable one.
Alternatively, perhaps you could ask someone with a drive to image it onto a USB thumb drive for you and then re-install from there.
P.S. I very much like Stellarium because it can show the positions of even minor satellites of the planets. Perhaps I am weird.

I forgot to mention https://aladin.u-strasbg.fr/AladinLite/ which is my atlas of choice for anything outside the solar system. Searchable, goes down to mag 21 or so, precision astrometry and photometry from Gaia, stars, clusters and fuzzies — what more could a deep sky observer want?
