[INSTALL] check for mp4 codecs requirement during installation

[udance4ever]

I installed the “N” version of Windows hoping it would reduce bloat.

Turns out a lot of applications (not just Retrobat) assume Windows Media Player is installed.

Retrobat requires Media Media Player to display the splash video.

Two items:

1. Retrobat should clearly display an error message if Media Player is not installed instead of allowing user to double click and nothing happening (tried on the command line as well, you execute it and it just comes right back without any error message)
2. installation should add Windows Media Player to the list of prerequisite checks (and should install the Media Feature Pack if needed (or request the feature be added))

Hello,
It's not windows media player that is required, but the codecs required to play mp4 video.
Some emulators will also not work with N versions.
Nothing much we can do here...

you can't check for the required codecs during install?
