What do you do when you insert a movie in a PowerPoint slide that refuses to play? There could be any number of reasons for it not to play, but more often than not, it has more to do with a missing codec than anything else!
Luckily, that’s one of the easiest problems to solve. And we don’t want you to download every single codec one after the other, not when you can download and install a pack of popular and some not-so-popular codecs at one go using the K-Lite Codec Pac that you can download free from the free-codecs site.
As the screenshot above shows, the installation routine even allows you to choose which codecs you want to install.
Thanks to Mike Parkinson for this tip!
