Hello I want to watch a video on my laptop what sd on a sd card is now this message. What can I do now?
This means that your video player does not support the respective data format. Therefore you have to download a video player which can play .AVI files.
Windows can open the Avi format
Not necessarily, in my experience some videos work more with Windows Media Player than the new Groove Player on Windows 10.
Download the best Vlc Media Player down, it should work
You could try the benign version of the Windows Media Player, the VLC Media Player.
You can install codecs
