Hey Ramin,
I think it is alright to install it and run it properly... but just for making sure... after u finished installing, try to run the setup file again and then repair... coz that seems to work better after what happen to mine last time... but last time i have different kind of error... but now it works fine after i run the setup another time and repair it... so i guess it will be the same thing as this one!!
p/s: I see GCU in ur desktop!! are u doing C++?? What kinda compiler do you use?? I have been trying to download g++ and emacs... but i always got the wrong files downloaded.. so not sure where to download it anyway!
