Hey All,

A customer ran into an issue with excel it was 'The file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create and association in the Default Programs control panel'

Here are a few articles I sent over for them to fix the issue as well as a YouTube visual.
