Old software but it works. You might find it close-out on
eBay. Doesn't handle big files very well because it's dated.
If you had PM enabled I'd send some links, but since you don't, that's the best I can do.
You can stitch the pan with some other software and generate the Java viewer with
Photovista Panorama version 3.5. This one was made with a 10D and it's a 360. After I compressed the file it works fine. Make sure it's 3.5 which was the last release.

I'm sure there are better things made now, but this one wins for simple and price. Not sure it will work with Vista.
