How do I edit my Power point template?

I downloaded a power point template but I can not edit the header that has the title of the owner who created it and the default website. Please help as I have my presentation next week and need to edit it fast. I already added my content on my slides but it won’t be me edit the title of the actual template and I can’'t edit my website on each slide.

Hi

My personal opinion please check software requirements for working the power point template and use accordingly. Also you can check documentation how to use that template.

Thanks

You almost certainly just need to edit the master slide https://support.office.com/en-gb/article/what-is-a-slide-master-b9abb2a0-7aef-4257-a14e-4329c904da54
