Upgrading VMware View Composer to version 2.7 produces a Registry Key Permissions Error

The error appeared after upgrading the View Connection server to version 5, and I had just began to upgrade the View Composer Server to 2.7.
Searching through the VMware Knowledge Base, I found an article that doesn’t speak directly at VMware View, but does apply to VMware Products.
This is the error I received:
