I am attempting to render a powerpoint presentation from rmarkdown.
I downloaded this powerpoint template and associated files from sol-eng and am able to generate the powerpoint as is.
However, if I open the template and do view -> slide master
and adjust any of the slide master (i.e. change the background color), I get the error "The file may be damaged or it may have been created in a pre-release version of PowerPoint." when I attempt to render the powerpoint.
I am unclear why using the template as is vs changing the background would generate an error in making the powerpoint presentation.
I am not sure if this is due to either a rmarkdown issue or a powerpoint issue.
Any suggestions would be helpful:)
