Do I need to have both paypal standard and express checkout installed?

Hi,

I thought I must had paypal standard installed to use paypal express checkout.
Am I right?

Do you have both paypal standard and express checkout as payment options for customers on your store?

Title: ALERT: PayPal Direct Payment Error (10565 <!-- -->)
Content: 10565 Merchant country unsupported. - The merchant country is not supported.

This is an urgent matter. Above is the junk mail we received for many times in several e-mail of our companies, and that's all for the mail. We don't know either which site of our company it came from or which person. And we received e-mails from somebody complaining they had tried so many times to buy things from our sites but failed that they had to give up and buy from others.

Wonder what the matter is and what should we do. If anybody can help, we'll appreciate it very much.

ericgu - no, you can use just Paypal Express.

Thanks, Stevesh

Another question:

I always receive 10417 alerts and some other alerts from paypal, which tells me there are people have trouble completing checkout with paypal express checkout option.

Before I used to suggest clients to try with paypal standard checkout when they encounter such problems.

Do you think it help or not by switching to standard checkout in these cases?
