Stream Laptop for Christmas – looking to add Windows Gallery – Having hard time.

Hello,

My husband bought an HP stream for me this past Christmas.  

It has Windows 8.1

I've searched but there is no Windows Gallery on here like I had on my older tower computer.

I'm not having any luck with the download, it just keeps cycling in it's little window stating that it is 

preparing to install.

I've waited for a good while and then had to ctrl alt delete to get it to cancel.

I'm not sure if I'm looking at the right download or if settings somewhere that I should have on are off or 

visa versa.

Anybody know where I can find this information?

Thanks kindly.
