connection problem in ST Motor Profiler

Hello,

I am using a nucleo-f302r8 and x-nucleo-ihm07m1 in order to controll a BLDC motor. I have installed the (ST Motor control workbench). when I run the st motor profiler and try to connect, I see the following message:

"unable to identify the exact number of boards connected by means of ST-LINK"

I have installed and upgraded ST-LINK usb driver properly. I use windows 10.

I appreciate your help to solve this connection problem
