Can't use gvim with pathogen under windows

Question

I have pathogen setup and working fine under Linux, but when I try to use the some configuration with gvim73 under windows it doesn't work at all. I don't get any errors but it does nothing.

Here is my dotfiles repository up on git. I've checked this out to ~/vimfiles and I added the following to _vimrc:

filetype off
call pathogen#helptags()
call pathogen#runtime_append_all_bundles()

I've tried just about everything including putting the autoload/pathogen.vim and bundles/ folders in the /vim73 directory under program files. Nothing.

Does anyone have some experience with this? I'm assuming there is something windows specific that needs to happen to make this work.

Edit: It is probably also worth noting I can run pathogen#runtime_append_all_bundles() even using tab completion so pathogen is being loaded, but my plugins are just not working.
