helix-player and RealPlayer

[Gerard Robin <g.robin3@free.fr>]

Hello,
I installed helix-player in my box, but when I want to play an mp3 file
it complains that RealPlayer is not present. 
Ok, I downloaded RealPlayer and ran RealPLayer10Gold.bin in /home/user1/ 
and now /home/user1/RealPLayer/realplay runs fine, but when I run 
helix-player it deosn't find realplay. 
Can someone explain to me where I must install the directory ReaPlayer 
and the files contained in it, so that helix-player finds reaplay  and
user2, user3 ... can play helix with RealPlayer ?
