Hi,

I successfully installed Episerver Commerce by following the steps provided in Episerver World website. When I try to launch Episerver CMS, I get Socket Exception "An attempt was made to access a socket in a way forbidden by its access permissions". Am I missing any special permission for folder where the Episerver Commerce solution is residing? Kindly, help me to resolve this issue, let me know if more details required. Please find below the complete stack trace of the exception.
