I don't think that is anomalous in itself. Install paths and home
directories are distinct concepts. But could you perhaps prepend
something like

SET > c:/TEMP/envir.txt

(I'm very rusty on Windows, but I think that should work) and tell us
what the variables are set to?

Btw, there's a user-friendlier way of setting environment variables on
XP isn't there?
