couldn't run my prepared presentation. I have a new power point on my computer where there is a pptx extension, but at school our computers will only open the older ppt extension. Here, I learned until recently that if I don't know the environment, I already save everything in both formats to avoid complications. Fortunately, I had a laptop in my office, for which I quickly adjusted the presentation to the correct format and started the class two minutes late.
