Introduction

A “Class not registered” error may occur on a K2 System when a Non Windows OS system is connected to an NLB cluster (i.e. a Linux Mail server). This is caused by the K2 Web Designer activation trying to create a virtual directory on the Non Windows OS system.

The error has been fixed by changing the logic by which the activation gets done for the K2 Web Designer.
