Hi,
For all those encountering issues with opening the PowerPoint presentation, please first save the file on your computer. Then, right-click on the file and choose the "open with" option. From there, select "open with Internet Explorer." The presentation should now open on your computer.
Next, navigate to the "save as" option and in the "save as type" drop-down menu, choose "PowerPoint Presentation" before saving the file. This will ensure that the presentation is saved correctly.
Best of luck with your presentation, and enjoy it!
Kind Regards,
qb
