Cannot execute git command from within gvim, but works in cmd window

I am trying to install Vundle in gvim on windows. When I run the :PluginInstall command, each of the plugins fails. When I look at the log it gives the following error message:


Plugin gmarik/vundle
git clone --recursive "https://github.com/gmarik/vundle.git" "C:\Users\snrub\vimfiles\bundle\Vundle.vim\vundle"
> Cloning into "C:\Users\snrub\vimfiles\bundle\Vundle.vim\vundle" ...
> fatal: unable to access 'https://github.com/gmarik/vundle.git/': SSL certificate problem: self signed certificate in certificate chain
>

However, if I copy the git clone command and paste it into a cmd window and run it it works fine. I tried to google the error message but nothing turns up. Why is it working in cmd but not gvim?
