Create a batch file and write code like this
@echo off
assoc .mpeg=YourVPlayer
assoc .mp4=YourVPlayer
assoc .mp3=YourVPlayer
assoc .wav=YourVPlayer
[Write all the extensions that your software supports
type YourVPlayer=[Your software exe file path]
save as anyname.bat
You can use in you vedio player setup file or SFX file and run it automatically after installation
I think usefull.
