Cannot run Lightroom on a new MacBook Pro

It loads the splash screen, then the window of lightroom with gray background (no sign) and then an error message saying "an error occurred when attempting to change modules".

I tried both with Lightroom 5.3 and 5.4

Any help?

Thank you very much!

specifications of the computer:

MacBook Pro 15 inch end 2013 retina

16GB 1600 Mhz DDR3 memory

Intel Iris Pro 1024 MB graphics card
OS X (13 1021 10.9.2
