Permission Denied - 3D PDF Template Editor

Hello,
When trying to publish to a 3D PDF from Solidworks MBD I get a "Permission denied on themes folder" error. See attached for popup.

I do not know where the 'themes' folder is.
I do not know where to grant permissions

I will try re-installing SW to see if it fixes it but I like to put records down when I can, and couldn't find one on this particular issue.
