Creating a certificate (openssl) for shopping site

SOLVED IT! i had downloaded the openssl files and i searched for the file it was wanting to directory it was looking at (ie c:\lan..) and voila it worked!!

I am trying to integrate paypal with my shopping site and have been following instruction on its site..

it asked me to type following in my dos and I did and it created a key..

openssl genrsa -out my-prvkey.pem 1024

It then asked me to type following to create a certificate and when i do that it gives me the error

openssl req -new -key my-prvkey.pem -x509 -days 365 -out my-pubcert.pem

error is:
"Unable to load config info from C:/lan/ssl/openssl.cnf"

I was wondering do i have to install the openssl software on my computer...
