So, you’re absolutely sure PowerPoint is sitting nicely on your computer… but then you double-click a PowerPoint file and — ta-da! Instead of opening in PowerPoint like a well-trained puppy, it either refuses to open or jumps into some other random program you didn’t invite to the party. No need to scream “What is happening?!” This simply means your computer has gotten confused about who should open that file. Think of it like your mail carrier delivering your favorite pizza to your neighbor’s house — the pizza exists, but it’s not reaching you.
