Error Message "Error creating Excel instance: Exception: Invalid class string (2147746291)" when using Excel step in CEF Robot

3025017

Question / Problem: 

When I try to use an Excel step in a CEF robot then I receive the error message "Error creating Excel instance: Exception: Invalid class string (2147746291)".

How can this be solved?

Answer / Solution: 

This error message is seen if Excel is not installed to the machine where the robot is started.

The excel step in Desktop Automation robots need an installed version of Excel to be able to work.
