unchecked all the protected view settings in the trust center, set my computer
to authentication and impersonation to connect and identify, enabled macros and
activeX controls, added the upload path to trusted settings, right-clicked the
PPTX, properties, but there is no "unblock" to unblock.
Nothing has fixed the issue.
What else can I check or is this just a bad PPTX since it's the only one we've found like this?
