Analysis Cubes Upgrade Dynamics GP Error in Cube - Unhandled Object Exception Class not registered

So you have upgraded Analysis Cubes for Dynamics GP and then go into GP to Microsoft Dynamics GP>> Tools>> Analysis Cubes>>Create Pivot Reports and when creating a new pivot, you click save and get an unhandled object exception: class not registered.

This is due to not having excel on the machine you are trying to deploy on. Use another machine.
