I've installed 1.3.7 and enabled PayPal Express. Unless I'm mistaken, I don't have the PP Ex option until I've already signed in or created an account in my ZC.
This is counter to the explanation:
which hints that a new customer can go directly to PP Ex. How do they get to PP Ex before they log in?New Customers
If the customer visiting your store doesn't already have an account and uses PayPal Express Checkout, an account is created automatically for them, and their password is emailed to them in the Welcome Email which sends when they return from the PayPal site after entering their PayPal login details and selecting their funding/shipping options.
Thanks,
