Hello for anyone having an issue opening this type of file on their mac all you'll need to do is download PowerPoint from the app store on ur mac. and then try opening the file again, that should do the trick. Although u will need a Microsoft login.
MacBook Air 13″, macOS 11.4
Is there a reason you have decided to post this information on the Mac OS X 10.7 Lion Community.
The version of Powerpoint available for download on the App Store requires a mac running at least macOS Mojave 10.14.
Therefore your post has no benefit for those running Mac OS X Lion 10.7 or any older OS's up to macOS High Sierra 10.13.
Even your own profile states you are running macOS Big Sur 11.4.
Perhaps you could post this information in a relevant community.
