Alienware 15 R2 missing AlienFX, Alienware TactX and Alienware Command Center

Hello everyone,

I'm looking for help with the following problem: I have noticed missing AlienFX on my computer. I play quite rarely so I have not noticed when it has happened, so it is hard to use some older system copy, however I have noticed today that AlienFX and Alienware TactX are missing in my task bar. I have check the system files, only things left are folders with saved themes. Only thing remaining after the Alienware Command Center is .msi file which cannot be started. What should I do?

Cheers!
