:help rtp
I can't determine from the vim documentation when 'runtimepath' is
set, although it appears to be before vimrc is sourced, so as you
have discovered, setting $HOME in vimrc doesn't affect
'runtimepath'. One solution would be to set $HOME before vimrc is
sourced, if that's possible in your situation. Another solution is
to set or edit 'runtimepath' in your vimrc, e.g.,
let &rtp = substitute(&rtp, "$HOME", 'E:/Apps/_conf/vim', 'g')
I have edited my 'runtimepath' in this way on one of my systems, but
I've not tested the specific example above.
HTH,
Gary
