Problem in installing paypal

Hello,
I want to install paypal. But when I clicked on install I am getting this error “Duplicate name Module Def Paypal Integration”. Can you please give me solution for this?

It seems you might have tried installing PayPal app before. where are you hosted?

I also have this problem… my first installation have payment gateway missing. How can i reinstall it?
