Cannot install matlab r2012A on mac 10.9.5

Hey!

Have been using Matlab for some years now, but recently i could not open it anymore. I decided to uninstall and download again, and now I cannot open the program InstallForMacOSX.app. I see only a little Matlab image and then it disappears.

On console i get the messages:

1) Dock: no information back from LS about running process LSASN:{hi=0x0;lo=0x75075}

2) Core ServicesUIAgent: Error: qtn_file_apply_to_path error: Read-only file system

Don't know what to do... tried repairing disk permissions but nothing happened.
