I dont see why it isnt working , but you shouldnt need to install any ogg player on any computer , all you need is the OggDS0994.exe thats included in your gamestudio installation. Now , you DO however have to install the codec on each machine that will play the ogg files , this might sound like a pain but it really isnt , as there is Install makers that allow you to run an external program during the game installation , so you can make the ogg codec installation be a part of the game installation , so anyone who installs the game will install the codec anyway , so you shouldnt have problems with people playing the music. I am currently using the ogg format for my games and using the ogg codec install during the game install and havnt had one problem with people not hearing the music. Though I will say that i use Tripple X mp3.dll plugin to play my ogg files because I only have extra edition which can only play mid or wav. Try installing the codec on the laptop and see if that fixes your problem.
