Problems with usb drivers using IAR embedded workbench

Question asked by de_vivo.riccardo on Dec 16, 2014
Hi i'm an italian student and i have to use IAR (for ARM) for c/c++ programming to control the stm32f401.
I'm trying to run a simple example program but i get always this error (i'm running windows 7 and i've tried it on different machines):
