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):

Tue Dec 16, 2014 12:13:45: Loaded macro file: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.0\arm\config\debugger\ST\STM32F4xx.dmac 

Tue Dec 16, 2014 12:13:45: Loaded macro file: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.0\arm\config\flashloader\ST\FlashSTM32F4xxx.mac 

Tue Dec 16, 2014 12:14:00: Fatal error: Failed to search for probes, ensure that the USB drivers are installled.   Session aborted! 

Tue Dec 16, 2014 12:14:00: Failed to load flash loader: C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.0\arm\config\flashloader\ST\FlashSTM32F401x.flash 

Thanks.
